1. What is the largest bone in the human body?

• A. Femur (thigh bone)
• B. Tibia (shin bone)
• C. Humerus (upper arm bone)
• D. Scapula (shoulder blade)

Correct answer: A

Rationale: The femur, also known as the thigh bone, holds the title of the largest bone in the human body. Situated in the upper leg, the femur plays a vital role in supporting the body's weight and enabling movement. While the tibia (shin bone), humerus (upper arm bone), and scapula (shoulder blade) are all essential bones, none of them match the femur in terms of size and importance. The tibia, humerus, and scapula are comparatively smaller bones with specific functions in their respective areas of the body, but they do not surpass the femur in size or significance.

2. In the sentence 'Singing is my favorite activity,' how does 'Singing' function in terms of parts of speech?

• A. Verb
• B. Noun
• C. Adjective
• D. Pronoun

Correct answer: B

Rationale: In the sentence provided, 'Singing' is a gerund, which is a verb form ending in -ing that functions as a noun. It represents the action of singing, but in this context, it acts as the subject of the sentence. Therefore, 'Noun' is the correct answer. 'Verb' (choice A) is incorrect because while gerunds are verb forms, in this sentence, 'Singing' is not acting as a verb. 'Adjective' (choice C) is incorrect as it describes a noun, which is not the case here. 'Pronoun' (choice D) is also incorrect as 'Singing' does not replace a noun in this sentence.

3. A sandwich shop earns $4 for every sandwich (s) it sells, $2 for every drink (d), and $1 for every cookie (c). If this is all the shop sells, which of the following equations represents what the shop’s revenue (r) is over three days?

• A. r = 4s + 2d + 1c
• B. r = 8s + 4d + 2c
• C. r = 12s + 6d + 3c
• D. r = 16s + 8d + 4c

Correct answer: A

Rationale: Let s be the number of sandwiches sold. Each sandwich earns $4, so selling s sandwiches at $4 each results in revenue of $4s. Similarly, d drinks at $2 each give $2d of income, and cookies bring in $1c. Summing these values gives total revenue = 4s + 2d + 1c. Therefore, option A, r = 4s + 2d + 1c, correctly represents the shop's revenue. Choices B, C, and D are incorrect because they incorrectly multiply the prices of each item by more than one day's sales, which would overstate the total revenue for a three-day period.

4. What is the primary function of the large intestine?

• A. To digest food
• B. To absorb water and form feces
• C. To absorb proteins
• D. To regulate blood pressure

Correct answer: B

Rationale: The correct answer is B. The primary function of the large intestine is to absorb water from digested food and form feces for elimination. It does not primarily digest food, absorb proteins, or regulate blood pressure. Choice A is incorrect because the large intestine does not digest food but rather absorbs nutrients and water. Choice C is incorrect as the absorption of proteins primarily occurs in the small intestine. Choice D is incorrect as the regulation of blood pressure is not a primary function of the large intestine.

5. What is the role of the large intestine in the digestive system?

• A. To break down proteins
• B. To absorb water and form feces
• C. To digest fats
• D. To neutralize stomach acid

Correct answer: B

Rationale: The correct answer is B. The large intestine plays a crucial role in absorbing water from indigestible food matter and forming feces for elimination. Choice A is incorrect because the breakdown of proteins primarily occurs in the stomach and small intestine. Choice C is incorrect as the digestion of fats primarily occurs in the small intestine. Choice D is incorrect as neutralizing stomach acid is mainly the function of the stomach lining and not the large intestine.
