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.

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.

Blood Pressure Regulators
The body is composed of systems that have evolved and diversified in order to maintain the natural functions and processes they regulate. One such system that has these regulators is the bodyĆ¢Ä‚¬Ä„¢s cardiovascular system. The bodyĆ¢Ä‚¬Ä„¢s pump, which regulates the flow of vitally needed oxygen to all cells of the body, as well as the discard of carbon dioxide and other waste products, is the heart.
Because blood pressure varies at different points within the body, differing components are needed to keep the bodyĆ¢Ä‚¬Ä„¢s blood pressure regulated. Three of the basic components are baroreceptors, chemoreceptors, and the kidneys.
Baroreceptors are stretch receptors composed of fine branching nerve endings and are contained along the walls of the arteries near the heart and in other areas of the body as well. Impulses are related to this stretching along the arterial walls, which causes these baroreceptors to send out even more impulses to the heart, arteries, and veins, causing the blood pressure to go either up or down.
Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level, carbon dioxide, and pH. Just think! A fall in oxygen causes receptors to send impulses to raise the blood pressure.
The kidneys play a role in regulating blood pressure by absorbing salts and water and removing wastes. Hormones secreted by the adrenal cortex cause the kidney to keep or let go of any salt and water. This has an influence on blood volume and consequently on blood pressure.
What is the primary purpose of the writer in this passage?
- A. To inform the reader about the dangers of high blood pressure
- B. To inform the reader how high blood pressure leads to a higher risk of heart attack
- C. To inform the reader how the cardiovascular system regulates blood pressure
- D. To persuade the reader that controlling one's blood pressure is important
Correct Answer: C
Rationale: The primary purpose of the writer in this passage is to inform the reader about how the cardiovascular system regulates blood pressure. The passage discusses the different components involved in regulating blood pressure, such as baroreceptors, chemoreceptors, and the kidneys. It explains their roles in maintaining blood pressure levels within the body. There is no direct focus on dangers of high blood pressure, heart attack risks, or persuading the reader to control blood pressure, making option C the correct choice.
Subjective exams measure your ability in several areas. Besides recall information, you must be
able to realize content logically and intelligently express yourself in a clearly understood manner. Subjective test provide opportunity for students to show their broad knowledge of a subjective
area. Answers may be in the form of paragraphs or lengthy essays. When your review for an essay exam, concentrate on main ideas rather than details. Since essay tests are less to a few questions, they are likely to deal with more important ideas of a subject. Prepare a list of question you think might be asked. Write an answer to each of your questions. Rather than writing complete sentence down your thoughts in outline form. Doing so will help
you organize the information so that you can express yourself clearly.
When you take the test, read through all the questions before you start to write. Allot time for each question, spending more time for questions worth the most points. Read each question carefully to determine exactly what they are asked. Pay attention to words such as define, illustrate, explain, list, compare, and contrast. Each work requires a different type of response. Write a brief outline of your answer on scrap paper or the back of the test. Make sure you include all the important ideas that are within the limits of the question. In other words, do not write more than is asked for each answer. When you write your answer, keep it specific and as brief as possible. In the introductory sentence it is often helpful to make a general statement that includes
important points addressed in each question. Such a topic sentence serves as a framework for your answer. Then use your outline to develop the main point and subtopics. Add substance to
your answer by including as many facts as possible to support your answer.
Check your paper before you submit it. Look for mistakes in grammar, spelling, sentence
structure, and punctuation. Unless you are certain an answer is wrong, do not change it. Your answer is an educated guess and is usually your best chance of answering correctly
Compared to objective exams, essay tests contain
- A. no good answers
- B. more questions
- C. fewer questions
- D. harder questions
Correct Answer: C
Rationale: Essay tests typically contain fewer questions compared to objective exams. This is because essay questions require more elaborate responses, often in the form of paragraphs or essays. Due to the depth of analysis and critical thinking needed to answer essay questions, a smaller number of questions are usually presented in the exam. Therefore, students should focus on understanding the main ideas and expressing them clearly to effectively tackle the fewer but more comprehensive essay questions.
The Summer Olympic Games. Once every four years the countries of the world send their best and brightest to participate in the Summer Olympic Games. The site for the event is decided years before, and most countries contend strongly for the privilege to host the Games. The 2008 games were held in Bejing, China.
There is a lot of pageantry and tradition attached to the event. The opening ceremony is elaborate and awe-inspiring. China put on a spectacularly beautiful fireworks display to welcome the world's athletes in 2008.
The track events, water events (swimming, diving) and precision activities such as archery and rhythmic gymnastics are wonderful to watch. Seeing these athletes perform their special skills is a treat for those of us who achieve a vicarious satisfaction from it. Everyone roots for the athletes from their own country and we thrill when our anther is played during the medal ceremony. Being an Olympian is an honor every athlete dreams of.
How often are the Summer Olympic Games held?
- A. Every two years.
- B. Every four years.
- C. Annually.
- D. Once a decade.
Correct Answer: B
Rationale: The Summer Olympic Games are held 'once every four years,' as stated in the text. This timeframe allows countries to send their best athletes to participate. The correct answer is B, 'Every four years,' making it a significant and eagerly anticipated global event. The four-year interval also allows for ample time for countries to prepare, build excitement, and showcase their best talents on a world stage.
The White Elephant: Centuries ago, In Siam, now known as Thailand, it was the custom of the rulers to give a white elephant to those who displeased them. The recipient could not give the elephant to anyone else, as it was a gift from the ruler, who would be greatly displeased should the recipient not receive the gift graciously or care for the elephant in a grand style. This monetary burden could be a major liability to the recipient and in many cases the entire family became impoverished.
This is the origin of the term 'white elephant' as it is used today to denote an unwanted gift. The parlor game of gift exchange played during the holiday season is an offshoot of this. In this game, everyone brings a wrapped gift and the gifts are exchanged by drawing numbers and picking a gift in turn. The second person can choose a new gift or steal the first one. It is all in good fun, and people enjoy giving silly gifts and 'stealing' someone else's gift.
How did the people regard a white elephant?
- A. If a village elder received a white elephant, the entire village shared in the supply of meat.
- B. The people of Siam vied for the honor of receiving the king's gift of a white elephant.
- C. People tried very hard not to offend the king so they would not receive a white elephant.
- D. White elephants were highly prized as they were very hard workers in the cane fields.
Correct Answer: C
Rationale: The correct answer is C because the passage states that receiving a white elephant was considered a burden, leading to potential impoverishment. This implies that people tried hard not to offend the ruler to avoid receiving such a gift. Option A is incorrect as it contradicts the negative consequences associated with receiving a white elephant. Option B is incorrect as the passage does not mention people actively seeking to receive a white elephant. Option D is incorrect as there is no mention of white elephants being valued for their work abilities in the passage.
Electrocardiogram
Beep!Ć¢Ä‚¬Ā¦Beep!Ć¢Ä‚¬Ā¦Beep! is the audible rhythmic sound made as the strength of the heart muscle is measured. The signal cadence has a characteristic record that varies in every individual. This record is called an electrocardiogram, or ECG.
In the body, an array of systemic neural responses constantly occur, emitting electric currents. The electric currents can be detected on the surface of the body, and if a person is hooked to an amplifier, these impulses are recorded by an electrocardiograph.
Most of the information obtained is about the heart because the heart sends out electric currents in waves. This Ć¢Ä‚¬Å“wave of excitationĆ¢Ä‚¬Ā¯ spreads through the heart wall and is accompanied by electric changes. The wave takes place in three distinct steps.
Initially, the Ć¢Ä‚¬Å“wave of excitationĆ¢Ä‚¬Ā¯ accompanied by an electric change lasts for approximately 1 to 2 seconds after the contraction of the cardiac muscle. The electric impulses are discharged rhythmically from the sinoatrial (SA) node, the pacemaker of the heart. This spread of excitation over the muscle of the atrium indicates that the atrium has contracted.
Next, the peak of the ECG reading is due to the atrioventricular (AV) node, causing the ventricle to become excited.
Finally, the ventricles relax, and any changes in the wave indicate to trained medical staff any abnormalities within the heart.
What are the three steps of the 'wave of excitation' during an electrocardiogram?
- A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
- B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
- C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
- D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.
Correct Answer: D
Rationale: The correct sequence of the 'wave of excitation' during an electrocardiogram includes the excitation of the atrium (contraction), the excitement of the ventricle (peak ECG), and the relaxing of the ventricle. This process starts with the discharge from the SA node, followed by the peak ECG due to the AV node, and ends with the relaxation of the ventricles. Understanding this sequence is crucial for interpreting ECG readings accurately and identifying any abnormalities within the heart.
