1. Tanya told her sister to tell her boyfriend Joe to call her as soon as he got home. Which of the following is a correct revision of the ambiguous sentence above?

• A. Tanya told her sister, 'Tell Joe to call me as soon as he gets home.'
• B. Her sister told her boyfriend Joe to call Tanya as soon as he got home.
• C. Tanya instructed her sister, 'Joe should call me when he gets home.'
• D. Tanya instructed her sister, 'Tell your boyfriend Joe to call me right after he gets home.'

Correct answer: D

Rationale: Option D provides a clear and concise revision of the ambiguous sentence with a straightforward instruction. Tanya asks her sister to relay a message to Joe, instructing him to call her immediately upon arriving home. The direct speech used in Option D clarifies the relationships and actions involved in the communication. Choices A, B, and C introduce confusion by altering the relationships and instructions given in the original sentence, making them incorrect.

2. Which of the following hormones is responsible for regulating blood sugar levels?

• A. Insulin
• B. Adrenaline
• C. Cortisol
• D. Melatonin

Correct answer: A

Rationale: Insulin is the hormone responsible for regulating blood sugar levels by facilitating the uptake of glucose into cells. Insulin helps lower blood sugar levels by promoting the storage of glucose in the liver, muscle, and fat cells. Adrenaline, cortisol, and melatonin do not directly regulate blood sugar levels. Adrenaline is involved in the fight-or-flight response, cortisol is a stress hormone that affects metabolism, immune response, and anti-inflammatory actions, while melatonin regulates sleep-wake cycles.

3. Susan bought a dress for $69.99, shoes for $39.99, and accessories for $34.67. What was the total cost of her outfit?

• A. 139.65
• B. 144.65
• C. 145.55
• D. 144.65

Correct answer: B

Rationale: To find the total cost of Susan's outfit, you need to add the prices of the dress, shoes, and accessories together. $69.99 + $39.99 + $34.67 = $144.65. Therefore, the correct total cost of her outfit is $144.65. Choice A ($139.65) is incorrect as it does not account for the full cost of all items. Choice C ($145.55) is incorrect as it includes an extra amount not part of the given prices. Choice D ($144.65) is incorrect due to a duplication of the correct answer.

4. Which of the following blood vessels contains the least oxygenated blood?

• A. Aorta
• B. Vena cava
• C. Pulmonary artery
• D. Femoral vein

Correct answer: C

Rationale: The correct answer is C: Pulmonary artery. The pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation. This blood is considered the least oxygenated in the body as it has just returned from circulating through the body's tissues and is in need of oxygen replenishment. Choice A, the aorta, is incorrect as it carries oxygenated blood from the heart to the rest of the body. Choice B, the vena cava, carries deoxygenated blood from the body back to the heart. Choice D, the femoral vein, also carries deoxygenated blood back to the heart from the lower extremities.

5. Which muscle causes a joint to bend?

• A. Cardiac
• B. Extension
• C. Flexor
• D. Smooth

Correct answer: C

Rationale: The correct answer is C: Flexor. A flexor muscle contracts to bend a joint, such as bending the elbow or knee. Flexor muscles are responsible for flexing or bending a joint, while extensor muscles are responsible for extending or straightening a joint. Choice A, Cardiac, is incorrect as cardiac muscle is found in the heart and is responsible for pumping blood. Choice B, Extension, is incorrect as extension refers to the straightening or extending movement of a joint, which is opposite to bending. Choice D, Smooth, is incorrect as smooth muscles are involuntary muscles found in organs like the intestines and blood vessels, not directly responsible for bending joints.
