1. Based on this passage, what can the reader infer about the advice physicians will give their pregnant patients about coffee consumption?

A. Almost all of them will advise women to stop drinking any caffeine until after the baby is born.
B. The majority will ignore the study altogether and continue to advise caffeine in moderation as before.
C. All of them will demand additional research be done before they change what they tell their patients.
D. Some will continue to make their normal recommendations about caffeine, while others will be more cautious than before.

Correct answer: D

Rationale: The passage implies that there is variability in physician responses to the study about caffeine consumption. Some doctors may continue their standard recommendations, while others might advise more caution based on the new evidence. Therefore, option D reflects this variability in professional opinions and is the correct inference.

2. What is the result of dividing 4 7/8 by 1 1/6?

A. 4 5/28
B. 4 7/8
C. 5 8/14
D. 5 3/28

Correct answer: A

Rationale: To divide mixed numbers, convert them to improper fractions and then multiply by the reciprocal of the divisor. Here, 4 7/8 = 39/8 and 1 1/6 = 7/6. Dividing 39/8 by 7/6 gives 39/8 ÷ 7/6 = 39/8 * 6/7 = 234/56 = 4 5/28. Therefore, the correct answer is A. Choices B, C, and D are incorrect as they do not represent the correct result of dividing 4 7/8 by 1 1/6.

3. Which of the following describes the process of osmosis?

A. Diffusion of solutes across a membrane
B. Movement of water across a selectively permeable membrane
C. Movement of gases across a membrane
D. Active transport of ions across a membrane

Correct answer: B

Rationale: Osmosis is the process where water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement of water helps to equalize the concentration of solutes on both sides of the membrane. The correct description of osmosis is the movement of water across a selectively permeable membrane, making choice B the right answer. Choices A, C, and D are incorrect because osmosis specifically refers to the movement of water molecules, not solutes, gases, or ions across a membrane.

4. Which of the heart's four chambers is the largest and the strongest?

A. Right atrium
B. Left ventricle
C. Right ventricle
D. Left atrium

Correct answer: B

Rationale: The left ventricle is the largest and strongest chamber of the heart. It pumps oxygenated blood to the body, making it vital for systemic circulation. The right atrium receives deoxygenated blood from the body, the right ventricle pumps this blood to the lungs, and the left atrium receives oxygenated blood from the lungs.

5. A blood vessel that is distended is ___________.

A. overturned
B. swollen
C. twisted
D. overlong

Correct answer: B

Rationale: A blood vessel that is distended is swollen. Distention refers to the state of being stretched beyond normal limits, which can cause the blood vessel to expand and swell. The term 'distended' is often used to describe blood vessels that are enlarged or swollen due to various reasons such as increased blood pressure or blockages. Choice A, 'overturned,' does not relate to the enlargement or swelling of a blood vessel. Choice C, 'twisted,' describes a different condition where the blood vessel is coiled or rotated, not necessarily enlarged. Choice D, 'overlong,' does not accurately describe the state of a distended blood vessel; instead, it implies excessive length rather than enlargement.
