1. Which of the following is responsible for transporting oxygen in the blood?

• A. White blood cells
• B. Red blood cells
• C. Platelets
• D. Plasma

Correct answer: B

Rationale: Red blood cells are responsible for transporting oxygen in the blood. Hemoglobin, a protein found in red blood cells, binds to oxygen in the lungs and carries it to tissues throughout the body. White blood cells are involved in the immune system's defense mechanisms against infections, platelets help in blood clotting, and plasma is the liquid component of blood that carries various substances like nutrients, hormones, and waste products.

2. How is power related to energy?

• A. Power is the same as energy
• B. Energy is the rate at which work is done
• C. Power is the amount of stored energy
• D. Energy is the rate at which power is transferred

Correct answer: B

Rationale: Energy is the capacity to do work, while power is the rate at which work is done or energy is transferred. Power is the amount of energy transferred or converted per unit time. Therefore, energy is related to power as the rate at which work is done. Choice A is incorrect because power and energy are not the same; they are related concepts but represent different aspects. Choice C is incorrect because power does not refer to stored energy but rather the rate of energy transfer. Choice D is incorrect because energy is not the rate at which power is transferred, but the capacity to do work or cause change.

3. Which version of the sentence is correct grammatically?

• A. I had seen her before, but yesterday was the first time I saw her indoors.
• B. I had saw her before, but yesterday was the first time I seen her indoors.
• C. I had seen her before, but yesterday was the first time I seen her indoors.
• D. I had saw her before, but yesterday was the first time I saw her indoors.

Correct answer: A

Rationale: The correct sentence is: 'I had seen her before, but yesterday was the first time I saw her indoors.' In this sentence, the correct past participle form of 'see' is used, which is 'seen' in the past perfect tense ('I had seen') and 'saw' in the simple past tense ('I saw'). Choices B, C, and D contain incorrect past participle and past tense forms of the verb 'see,' making them grammatically incorrect. Choice A is the only option that uses the correct past participle 'seen' and the correct simple past tense 'saw.' Therefore, it is the grammatically correct version of the sentence.

4. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B correctly uses a semicolon to join two independent clauses related to the same event. In this sentence, 'The guests arrived' and 'Sarah greeted them at the door' are both independent clauses that are appropriately connected using a semicolon. Choice A incorrectly uses a semicolon before 'however,' which is a conjunction that should be preceded by a comma. Choice C incorrectly uses a semicolon to connect two independent clauses that are not closely related. Choice D incorrectly uses a semicolon to connect two independent clauses without a clear relationship or cohesion.

5. Which term describes a position closer to the center of the body?

• A. Distal
• B. Proximal
• C. Lateral
• D. Medial

Correct answer: B

Rationale: The correct answer is B: Proximal. Proximal is used to describe a position closer to the center of the body. Distal, the incorrect choice, refers to a position farther away from the center. Lateral, another incorrect choice, indicates a position on the side of the body. Medial, also an incorrect option, describes a position towards the middle or midline of the body.
