1. Which of the following is NOT a major component of a healthy blood pressure reading?

• A. Systolic pressure (peak pressure during ventricular contraction)
• B. Diastolic pressure (pressure within arteries during ventricular relaxation)
• C. Pulse pressure (difference between systolic and diastolic pressure)
• D. Blood oxygen saturation levels. While blood oxygen levels are crucial for overall health, they are not directly reflected in a blood pressure reading.

Correct answer: D

Rationale: Blood oxygen saturation levels are essential for overall health but are not directly part of a blood pressure reading. A healthy blood pressure reading consists of systolic pressure, diastolic pressure, and pulse pressure. Systolic pressure represents the peak pressure during ventricular contraction, diastolic pressure reflects the pressure within arteries during ventricular relaxation, and pulse pressure is the difference between systolic and diastolic pressure. These components collectively provide information about the pressure variations within the arteries throughout the cardiac cycle phases, contributing to the assessment of cardiovascular health. Therefore, choice D, blood oxygen saturation levels, is not a major component of a healthy blood pressure reading and is the correct answer. Choices A, B, and C are major components of a healthy blood pressure reading and directly relate to the pressure variations within the arteries during different phases of the cardiac cycle.

2. While studying vocabulary, a student notices that the words circumference, circumnavigate, and circumstance all begin with the prefix 'circum'. The student uses her knowledge of affixes to infer that all of these words share what related meaning?

• A. Around, surrounding
• B. Travel, transport
• C. Size, measurement
• D. Area, location

Correct answer: A

Rationale: The correct answer is A: 'Around, surrounding.' The prefix 'circum-' commonly means 'around' or 'surrounding,' as observed in words like circumference (the distance around a circle), circumnavigate (to sail or travel around something), and circumstance (a condition surrounding or related to an event). Choices B, C, and D are incorrect because the shared meaning among these words is related to being around or surrounding, not travel, transport, size, measurement, area, or location.

3. Which of the following choices introduces a specific claim and distinguishes it from counterclaims?

• A. Is texting while driving really a critical safety issue? Are all kinds of distracted driving created equal? What can be said about the nature of distracted driving among teenagers?
• B. It's true that distracted driving is dangerous. There may be nothing more dangerous than texting while driving. Texting while driving has resulted in more than 15,000 deaths and over 200,000 injuries. The majority of texting drivers are teens, although other age groups have been implicated.
• C. Texting while driving is one of the key issues facing young people today: it's a fact that texting drivers have killed over 16,000 people between 2002 and
• D. While some argue that texting while driving is just one form of distracted driving, it stands out as particularly hazardous due to the level of focus it diverts from the road. Studies show that drivers who text are 23 times more likely to be involved in an accident compared to other forms of distracted driving.

Correct answer: B

Rationale: Choice B introduces a specific claim that texting while driving is extremely dangerous by stating that 'there may be nothing more dangerous than texting while driving' and supports this claim with statistics on the number of deaths and injuries caused by texting while driving. It further emphasizes the impact by mentioning that the majority of texting drivers are teens. This approach of providing specific evidence helps to distinguish the claim from counterclaims and strengthens the argument. Choices A, C, and D do not introduce a specific claim supported by factual evidence and fail to distinguish it from potential counterclaims, making them less effective in presenting a strong argument.

4. Which of the following sentences shows the correct use of quotation marks?

• A. "Grady asked Abe, 'Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?'"
• B. Grady asked Abe, 'Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?'
• C. Grady asked Abe, "Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?"
• D. Grady asked Abe, "Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?"

Correct answer: C

Rationale: The correct use of quotation marks is in option C. In this option, the entire quoted sentence is enclosed within double quotation marks. This is the standard convention for punctuating direct speech in English. Option A has an incorrect placement of single and double quotation marks. Option B lacks opening double quotation marks for the spoken sentence. Option D incorrectly places the closing quotation mark outside the question mark, which is not the standard punctuation rule for quoted sentences.

5. What determines the magnitude of the frictional force acting on a book sliding across a table?

• A. Only the mass of the book
• B. Only the normal force from the table
• C. Both the mass of the book and the normal force from the table
• D. Neither the mass of the book nor the normal force from the table

Correct answer: C

Rationale: The magnitude of the frictional force acting on the book sliding across a table is determined by both the mass of the book and the normal force from the table. Frictional force is proportional to the normal force (which is influenced by the weight of the book, i.e., its mass) and is affected by the surfaces in contact and other friction-related factors. Therefore, both the mass of the book and the normal force from the table are essential in determining the frictional force experienced by the book during its sliding motion. Choices A, B, and D are incorrect because friction is a result of the interaction between the surfaces and is influenced by both the mass of the object and the normal force acting on it.
