Anatomy
1. Micturition involves a combination of:
- A. Gravity alone
- B. Voluntary muscle contractions only
- C. Involuntary muscle contractions only
- D. Both voluntary and involuntary muscle contractions
Correct answer: D
Rationale: The correct answer is D: 'Both voluntary and involuntary muscle contractions.' Micturition, also known as urination, is a complex process involving both voluntary and involuntary muscle contractions. The voluntary muscle contractions allow us to control when we urinate, while the involuntary muscle contractions help to expel urine from the bladder. Gravity alone (option A) is not sufficient for micturition, as muscle contractions are necessary to empty the bladder. Similarly, relying on voluntary muscle contractions only (option B) would not be effective, as involuntary contractions are also needed to fully empty the bladder. Lastly, option C stating 'Involuntary muscle contractions only' is incorrect because voluntary muscle contractions play a crucial role in micturition. Therefore, option D is the most comprehensive and accurate choice.
2. What part of speech is the underlined word in the sentence "The students eagerly awaited the results"?
- A. Verb
- B. Noun
- C. Adjective
- D. Adverb
Correct answer: B
Rationale: Option B identifies "results" as the direct object of the verb "awaited," making it a noun.
3. A stop sign has five equal sides, each measuring 25cm. What is its perimeter?
- A. 100cm
- B. 125cm
- C. 150cm
- D. 175cm
Correct answer: B
Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 5 * 25cm = 125cm.
4. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?
- A. 1.4ml
- B. 2.1ml
- C. 2.8ml
- D. 3.5ml
Correct answer: D
Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.
5. What is the function of the pituitary gland?
- A. Produces hormones that regulate growth and metabolism
- B. Filters blood and removes waste products
- C. Stores and releases bile
- D. Produces red blood cells
Correct answer: A
Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

- A. The car moved slowly down the street.
- B. The car drove sluggishly down the road.
- C. The car inched down the avenue.

Correct answer: C
Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."
