1. On which day of the week will they be able to water their lawn?

• A. Tuesday
• B. Wednesday
• C. Thursday
• D. Saturday

Correct answer: B

Rationale: Based on the town's watering schedule, residents with addresses ending in 7 should water their lawns on Wednesdays. The Morgan family's address ends in 7, so they should set up their watering schedule for Wednesdays. Therefore, the correct answer is Wednesday. Choices A, C, and D are incorrect as they correspond to days designated for addresses ending in other numbers according to the town's schedule.

2. Which of the following represents an opinion statement on the part of the author?

• A. According to the CDC, tobacco products cause nearly six million deaths per year.
• B. Nicotine addicts sometimes pay more for a pack of cigarettes than gas.
• C. They risk staining their teeth and fingers with tar.
• D. Smokers tend to stink and create pervasive nastiness.

Correct answer: D

Rationale: The statement 'Smokers tend to stink and create pervasive nastiness' is an opinion since it reflects the author's subjective view on the hygiene and social impact of smoking. The other choices, A, B, and C, are all factual statements based on research or observations without expressing a personal viewpoint. Choice A presents a statistic from the CDC, choice B discusses a comparison related to the cost of cigarettes, and choice C describes a potential consequence of smoking without inserting personal judgment.

3. During gas exchange in the alveoli, what happens to oxygen?

• A. Oxygen is released from the alveoli into the bloodstream.
• B. Oxygen is absorbed from the alveoli into the bloodstream.
• C. Oxygen is converted into carbon dioxide.
• D. Oxygen is stored in the alveoli for later use.

Correct answer: B

Rationale: During gas exchange in the alveoli, oxygen is absorbed from the alveoli into the bloodstream. This process occurs due to the difference in partial pressures of oxygen between the alveoli and the bloodstream, causing oxygen to move from an area of higher concentration (alveoli) to an area of lower concentration (bloodstream). Oxygen is then transported by red blood cells to tissues throughout the body for cellular respiration. Choice A is incorrect as oxygen moves from the alveoli into the bloodstream, not the other way around. Choice C is incorrect as oxygen is not converted into carbon dioxide during gas exchange. Choice D is incorrect as oxygen is not stored in the alveoli but rather continuously exchanged with carbon dioxide during respiration.

4. Which of the following organs is NOT directly involved in urine production?

• A. Kidneys
• B. Urethra
• C. Lungs
• D. Bladder

Correct answer: B

Rationale: The correct answer is B, Urethra. The urethra is not directly involved in urine production. It is a tube that carries urine from the bladder to the outside of the body. The kidneys are responsible for filtering waste and excess substances from the blood to produce urine. The bladder stores urine until it is expelled from the body. The lungs are not involved in urine production; they are responsible for gas exchange during respiration. Choice A, Kidneys, is directly involved in urine production by filtering the blood to form urine. Choice C, Lungs, plays a role in respiration and oxygen exchange but is not directly involved in urine production. Choice D, Bladder, stores urine before it is excreted from the body and is directly involved in the final stages of urine elimination, unlike the urethra.

5. Where is the scaphoid bone located in the body?

• A. Wrist
• B. Shoulder
• C. Spine
• D. Face

Correct answer: A

Rationale: The correct answer is A: Wrist. The scaphoid bone is one of the carpal bones located in the wrist. It is a small boat-shaped bone that is frequently involved in wrist injuries, such as falls onto an outstretched hand resulting in a scaphoid fracture. Choices B, C, and D are incorrect as the scaphoid bone is not located in the shoulder, spine, or face. Understanding the anatomical location of bones is crucial for diagnosing and treating injuries accurately.
