1. A man can type 45 words per minute. How many words can he type in 20 minutes?

• A. 875 words
• B. 800 words
• C. 900 words
• D. 875 words

Correct answer: C

Rationale: To calculate the total number of words typed in 20 minutes, multiply the typing speed per minute (45 words) by the duration in minutes (20 minutes): 45 words/min × 20 min = 900 words. Therefore, the correct answer is 900 words. Choices A, B, and D are incorrect because they do not reflect the accurate calculation based on the given information.

2. What is the process of digestion?

• A. Production of enzymes
• B. The mechanical and chemical breakdown of food
• C. Absorption of nutrients in the blood
• D. Movement of enzymes

Correct answer: B

Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.

3. Which might be a result of stenosis, or narrowing of a heart valve?

• A. Abdominal pain
• B. Blood clots
• C. Edema (swelling) in organs
• D. Irregular heartbeat

Correct answer: D

Rationale: Stenosis, or narrowing of a heart valve, restricts blood flow through the valve, leading to changes in the heart's normal rhythm. This alteration can result in an irregular heartbeat, making it a common consequence of heart valve stenosis. Abdominal pain, blood clots, and organ swelling are not typically associated with stenosis of a heart valve.

4. Choose the meaning of the word progeny in the following sentence: 'This is a disease that is likely to recur in a patient’s progeny.'

• A. Chest
• B. Hormones
• C. Offspring
• D. Lifetime

Correct answer: C

Rationale: In the given sentence, the word 'progeny' means descendants or offspring. It refers to the children or future generations of the patient. Choice A, 'Chest,' is incorrect as it does not relate to the context of the sentence. Choice B, 'Hormones,' is also incorrect as it is not synonymous with 'progeny.' Choice D, 'Lifetime,' is unrelated to the concept of offspring, making it an incorrect choice.

5. Through which organ do muscles push food into the stomach via peristalsis?

• A. Mouth
• B. Small intestine
• C. Epiglottis
• D. Esophagus

Correct answer: D

Rationale: The correct answer is D, Esophagus. Muscles push food into the stomach via peristalsis in the esophagus. Peristalsis is a coordinated muscular contraction that helps move food from the mouth to the stomach through the esophagus. The rhythmic contractions of the esophageal muscles create a wave-like motion that propels food downward toward the stomach for digestion. Choices A, B, and C are incorrect because the mouth is where digestion begins but does not push food into the stomach, the small intestine is mainly responsible for absorbing nutrients, and the epiglottis is a flap that prevents food from entering the trachea during swallowing, not involved in pushing food into the stomach.
