1. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.

2. Identify the opposing muscle pair.

Correct answer: A

Rationale: The correct answer is A. The bicep and tricep muscles form an antagonistic muscle pair, where one muscle contracts while the other relaxes. The bicep, located on the front of the upper arm, is responsible for arm flexion (bending the elbow), while the tricep, situated on the back of the upper arm, is responsible for arm extension (straightening the elbow). This opposing action allows for controlled movement at the elbow joint. Choice B, hamstring and quadriceps, are not opposing muscles in the context of the knee joint; the hamstring group flexes the knee, while the quadriceps group extends it. Choices C and D do not represent an opposing muscle pair related to joint movement.

3. Which of the following phrases is grammatically correct and uses parallel structure?

Correct answer: B

Rationale: Option B is the correct answer as it uses the gerund (-ing) form for all three hobbies, achieving parallel structure. Parallel structure requires that elements in a sentence are grammatically balanced. In this case, all three activities are presented in the same form, making the sentence clear and consistent. Choices A, C, and D do not exhibit parallel structure as they mix verb forms or use infinitives, breaking the parallelism needed for correct grammar.

4. Which structure in the body is responsible for detecting light and converting it into signals for the brain?

Correct answer: B

Rationale: The correct answer is the Retina. The retina in the eye contains specialized cells called photoreceptors that detect light and convert it into neural signals. These signals are then transmitted to the brain via the optic nerve for visual processing. The iris is responsible for controlling the amount of light entering the eye by adjusting the size of the pupil, while the lens helps focus light onto the retina. The pupil is simply the opening in the center of the iris that allows light to enter the eye.

5. How many liters are in 750 milliliters?

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.
