People of Hispanic origin were on the North American continent centuries before settlers arrived
from Europe in the early 1600s and the thirteen colonies joined together to form the United
States in the late 1700s. The first census of the new nation was conducted in 1790, and counted about four million people, most of whom were white. Of the white citizens, more than 80%
traced their ancestry back to England. There were close to 700,000 slaves and about 60,000 "free Negroes". Only a few Native American Indians who paid taxes were included in the census count, but the total Native American population was probably about one million. By 1815, the population of the United States was 8.4 million. Over the next 100 years, the
country took in about 35 million immigrants, with the greatest numbers coming in the late 1800s and early 1900s. In 1882, 40,000 Chinese arrived, and between 1900 and 1907, there were more
than 30,000 Japanese immigrants. But by far, the largest numbers of the new immigrants were
from central, eastern, and southern Europe. An enormous amount of racial and ethnic assimilation has taken place in the United States. In 1908, play-write Israel Zangwill first used the term "melting pot" to describe the concept of a place where many races melted in a crucible and re-formed to populate a new land. Some years during the first two decades of the 20th century, there were as many as one million new
immigrants per year, an astonishing 1 percent of the total population of the United States.
In 1921, however, the country began to limit immigration, and the Immigration Act of 1924
virtually closed the door. The total number of immigrants admitted per year dropped from as many as a million to only 150,000. A quota system was established that specified the number of
immigrants that could come from each country. It heavily favored immigrants from northern and western Europe and severely limited everyone else. This system remained in effect until 1965, although after World War II, several exceptions were made to the quota system to allow in
groups of refugees.

Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy into chemical energy stored in sugar molecules. This process is fundamental to life on Earth as it provides the primary source of energy for nearly all organisms. The energy is captured from sunlight by a pigment in the plants called chlorophyll, which gives plants their green color.
During photosynthesis, carbon dioxide from the air and water from the soil react in the presence of light to form sugars and oxygen. The oxygen is released into the atmosphere, which is crucial for the survival of most life forms on Earth. The sugars produced are used by the plant for energy and growth, storing excess energy as starch.
The process occurs in two main stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of ATP and NADPH. The Calvin cycle uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.

What is produced in the Calvin cycle during photosynthesis?

• A. ATP
• B. Glucose
• C. Water
• D. Oxygen

The ebb and flow of laughter and silence fills the room as four old friends gather to engage in a
round of Bridge playing. For the beginner, Bridge can be complicated, but with time, effort, and a good teacher, even the novice can become proficient. Composed of two main parts, bidding and playing, Bridge requires the player's undivided attention. The dealer deals the entire deck of playing cards evenly between the for players, with
each person receiving thirteen cards. In the bidding portion of the game, the four suits of cards in the deck are ranked highest to lowest as follows: spades, hearts, diamonds, and finally clubs. However, during play all the suits of cards are
considered equals, and they go from highest to lowest from the ace being high to the two cards
being low. The highest number of tricks wins. A trick is one card played by each player for a
total of four. After the lead player lays down his/her card, the other players follow suit, if
possible. The highest card within the four "same suit" cards played wins the trick and picks up all
four cards. If a player cannot follow suit, he/she plays any card, but to make the game more
interesting and challenging, one suit is named a trump suit which means that if a player plays a
card from the trump suit, it always wins the trick. If two cards from the trump suit are played, the
highest card within the trump suit wins the trick. Obviously, the team with the most tricks wins
the hand.

According to the passage, which statement is explicitly stated?

• A. That the highest card within the "trump" suit always wins the trick.
• B. The Ace card is always the lowest card.
• C. That there is a pile of leftover cards that is placed in the middle of the game table.
• D. That if a player cannot follow suit, they lose the trick unless they play a card from the trump suit.

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.

Nurseries are:

• A. Special types of farms.
• B. Places where people go for medical treatment.
• C. Schools for young children.
• D. Stores that sell electronics.
