The Water Cycle Water is needed to sustain practically all life functions on planet Earth. A single drop of this compound is composed of an oxygen atom that shares its electrons with each of the two hydrogen atoms. The cycle starts when precipitation, such as rain, snow, sleet, or hail, descends from the sky onto the ground. Water that is not absorbed immediately from the precipitation is known as runoff. The runoff flows across the land and collects in groundwater reservoirs, rivers, streams, and oceans. Evaporation takes place when liquid water changes into water vapor, which is a gas. Water vapor returns to the air from surface water and plants. Ultimately, condensation happens when this water vapor cools and changes back into droplets of liquid. In fact, the puffy, cotton clouds that we observe are formed by condensation. When the clouds become heavily laden with liquid droplets, precipitation ensues.
According to the passage, which statement is false?
- A. Putty, cotton clouds are the result of a heat transfer process.
- B. The compound for a single drop of water is Hâ‚‚O.
- C. Water is an essential element for living things.
- D. Lake water is produced as a result of the runoff.
Correct Answer: A
Rationale: Statement A is false because "putty, cotton clouds" is not a recognized scientific term or phenomenon related to heat transfer processes. The other statements are true according to the passage, where it discusses the composition of water, its essential role in life, and the process of runoff.

It is a well-known fact that it takes the Earth approximately 365 days to orbit the Sun. At the same time, the Earth revolves or spins around itself over the course of 24 hours, which explains why we experience day and night. One half of the Earth is always facing the Sun, while the other half is facing away. As a result, different time zones divide the globe. Moving suddenly from one time zone to another, such as when flying from Asia to North America, can cause jet lag. People often feel tired, wake up suddenly during the night, and cannot return to sleep. It takes time to adjust to a new time zone. Another important factor to consider is the slight tilt of the Earth toward the Sun. The Earth does not stand straight but leans slightly to one side. Therefore, when it revolves around the Sun, the middle part of the Earth is always closer to the Sun and receives more heat. This area is called the equator, and the regions above and below it are known as the tropics. Countries located in the tropics receive a consistent amount of daylight throughout the year, with the Sun rising at 6 AM and setting at 6 PM. In contrast, the tips of the Earth, or the poles, receive hardly any light because they are so far from the Sun. There are two main seasons at the poles: 6 months of summer, when the Sun is always shining (even at night), and 6 months of winter, characterized by constant darkness. Between the tropics and the poles lies the temperate zone, where there are four distinct seasons. The Sun rises and sets at different times throughout the year. In spring and summer, it gets light earlier; in fall and winter, it gets dark earlier. People living in temperate zones take advantage of this variation to maximize their daylight exposure. At the beginning of spring, countries in Europe and North America readjust their clocks by moving them an hour ahead. As a result, the Sun does not set around 7 or 8 PM as usual, but an hour later. This practice is called Daylight Savings Time (DST) and lasts until the beginning of fall, when people move their clocks back one hour to Standard or Regular Time. It is believed that Benjamin Franklin first suggested the introduction of Daylight Savings Time in the 18th century, but the first serious proposal came in 1907 from William Willet. However, his idea was shelved by the British government, which deemed it unnecessary. Daylight Savings Time was first implemented by the German government in 1916 in order to save energy during World War I. Shortly after, the United Kingdom followed suit, with the United States doing the same in 1918. The law was unpopular, as people had to wake up earlier, leading many to experience a feeling similar to jet lag. However, the energy crisis of the 1970s forced the U.S. to establish Daylight Savings Time as law. Studies showed that the introduction of Daylight Savings Time in the spring saved the U.S. 10,000 barrels of oil per day between 1974 and 1975. It also prevented 2,000 traffic injuries and 50 traffic-related deaths, saving the country $28 million. Currently, Americans switch to Daylight Savings Time on the first Sunday in April and revert to Standard Time on the last Sunday in October. As of 2007, the time adjustments occur even earlier in March and November.
Was Daylight Savings Time popular in the beginning?
- A. Yes, people wanted to save energy.
- B. Yes, people like staying up late in the summer months.
- C. No, there was a war at that time and people hated it.
- D. No, people felt tired because they couldn't sleep that long.
Correct Answer: D
Rationale: Daylight Savings Time was not popular in the beginning. When it was first introduced, people experienced negative effects such as feeling tired due to having to adjust their sleep schedules. The rationale mentions that the law was very unpopular, people had to wake up earlier, and many experienced a feeling like jetlag. These challenges led to people not liking Daylight Savings Time initially.
A BIT ABOUT BICYCLES
Today, bicycles are so common that it's hard to believe they haven't always been around. But two hundred years ago, bicycles didn't even exist, and the first bicycle, invented in Germany in 1818, was nothing like our bicycles today. It was made of wood and didn't even have pedals. Since then, however, numerous innovations and improvements in design have made the bicycle one of the most popular means of recreation and transportation around the world. In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, dramatically improved upon the original bicycle design. Macmillan's machine had tires with iron rims to keep them from getting worn down. He also used foot-operated cranks like pedals, so his bicycle could be ridden at a quick pace. It didn't look much like a modern bicycle, though, because its back wheel was substantially larger than its front wheel. In 1861, the French Michaux brothers took the evolution of the bicycle a step further by inventing an improved crank mechanism. Ten years later, James Starley, an English inventor, revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient, and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top heavy, and ridden mostly for entertainment. It wasn't until 1874 that the first truly modern bicycle appeared on the scene. (14) Invented by another Englishman, H.J. Lawson, the "safety bicycle" would look familiar to today's cyclists. This bicycle had equal-sized wheels, which made it less prone to toppling over. Lawson also attached a chain to the pedals to drive the rear wheel. With these improvements, the bicycle became extremely popular and useful for transportation. Today they are built, used, and enjoyed all over the world.
What does 'taste' mean?
- A. Perceiving a sensation on the tongue
- B. A sensation in the tongue
- C. A liking
- D. Ability to enjoy what is beautiful and harmonious
Correct Answer: A
Rationale: The term 'taste' in this context refers to the action of perceiving a sensation on the tongue. When discussing taste in the context of sensory perception, it is related to the sense of taste that allows us to discern flavors. Option A, 'Perceiving a sensation on the tongue,' accurately defines the term in the given context. Options B, C, and D are not relevant to the specific meaning of 'taste' being referred to in this question.
ELECTORAL COLLEGE
The Electoral College has nothing to do with college and contains no students. The Electoral College consists of votes that each state acquires based on the number of representatives it has in Congress. Each state has two electoral votes because each state has two senators. The remaining electoral votes are determined by the number of Congressmen, the number of which is based on the population of the state established by the Census taken each decade. During the presidential election, most states cast all their electoral votes for the candidate who wins the popular vote in that state. It's all very confusing, but the founding fathers know what they were doing. Downloaded by Abdul Hamid (a.ahamid2181@gmail.com) lOMoARcPSD|10672023 HESI A2 V2 Grammar, Vocab, Reading, & Math Questions with Answers). By having and using the Electoral College candidates' campaign in every state, but just because they win the popular vote across the country doesn't mean they will always win the election. Case in point, in election 2000, Al Gore won the popular vote across the country, but George W. Bush won more electoral votes. Therefore, he became our 43rd president.
Which statement is a fact?
- A. Each state casts its electoral votes during the Presidential election.
- B. Every state always votes for the same candidate in every election.
- C. Electoral votes are only counted if a candidate has a majority in Congress.
- D. States can choose not to participate in the Presidential election.
Correct Answer: A
Rationale: The correct answer is A: 'Each state casts its electoral votes during the Presidential election.' This statement is a fact as during the Presidential election, each state does cast its electoral votes based on the outcome of the popular vote in that state. The Electoral College system involves states allocating their electoral votes to the candidate who wins the popular vote in their state. This process is a key part of the Presidential election in the United States, where electoral votes ultimately determine the winner. Therefore, this statement accurately reflects the process of how electoral votes are cast during the election.
Cystic fibrosis is a disease that is passed down through families. It is caused by a defective gene
that makes the body produce abnormally thick and sticky fluid, called mucus. This mucus builds
up in the breathing passages of the lungs and in the pancreas. The buildup of mucus results in
life-threatening lung infections and serious digestion problems. The disease may also affect the
sweat glands and a man's reproductive system. Millions of Americans carry a CF gene, but do
not have symptoms. This is because a person with CF must inherit two defective genes, one from
each parent. About 1 in 29 Caucasian Americans have the CF gene. It is more common among
those of northern or central European descent. Most children with CF are diagnosed by age 2.
For a small number, the disease is not detected until age 18 or older. These children often have a
milder form of the disease.
Which of the following describes the purpose of the passage?
- A. Describing the causes of cystic fibrosis
- B. Explaining how cystic fibrosis is passed down through families
- C. Providing an overview of the causes of CF and how it is carried
- D. Reviewing why some Americans have CF, but others do not
Correct Answer: C
Rationale: The passage serves the purpose of providing an overview of cystic fibrosis, including its causes and how it is inherited. It explains the genetic aspect of the disease and how it is passed down through families, emphasizing the need to inherit two defective genes to develop CF. The passage touches on the prevalence of the CF gene in the population and the age at which most children are diagnosed. Therefore, choice C, 'Providing an overview of the causes of CF and how it is carried,' best encapsulates the purpose of the passage.
Nurseries
If you thought nurseries were just for babies, well, think again! Being special kinds of farms, nurseries are used to raise plants in mass quantities. Plants, trees, and shrubs are typically grown in nurseries and then sold to farmers and gardeners to plant in homes, businesses and farms. Most nurseries are found in the more rural parts the country because much land is required to have a viable nursery. If a nursery sells plants to others, it must obtain a special permit from the local city or county, which keeps the competition fair and does not saturate the market with a large number of nurseries selling similar products.
Also on the grounds of nurseries are greenhouses which are made of glass or plastic panes that protect the plants from weather elements that may harm them and cause them not to grow and develop. The glass panels in greenhouses allow for sunlight to enter and moisture to be trapped inside. This creates a tropical environment which allows orchids and poinsettias to grow. It ensures that vegetables and fruits will grow large, which makes them valuable to farmers.
What are nurseries primarily known as?
- A. Special types of farms.
- B. Places where people go for medical treatment.
- C. Schools for young children.
- D. Stores that sell electronics.
Correct Answer: A
Rationale: Nurseries are primarily known as special types of farms where plants, trees, and shrubs are grown in mass quantities. These plants are then sold to farmers and gardeners for planting in various settings. The information provided in the extract clearly describes nurseries as agricultural establishments focused on plant cultivation, making choice A the correct answer.
