1. What can one infer about the meaning of the word 'Juggernaut' from the author's use of it in the passage?

• A. It is an apparition that appears at daybreak.
• B. It scares children.
• C. It is associated with space travel.
• D. Mr. Utterson finds it soothing.

Correct answer: B

Rationale: The word 'Juggernaut' is used metaphorically in the passage to describe a powerful and destructive force, as seen when the child is trodden down and left screaming. This metaphorical usage aligns with choice B, 'It scares children,' as it conveys the idea of something imposing and frightening. Choices A, C, and D are incorrect as they do not capture the negative and forceful connotation associated with the term 'Juggernaut' in the passage. Therefore, the correct answer is B.

2. The phone bill is calculated each month using the equation C = 50 + 75D. The cost of the phone bill per month is represented by C, and D represents the gigabytes of data used that month. What is the value and interpretation of the slope of this equation?

• A. 75 dollars per gigabyte
• B. 75 gigabytes per day
• C. 50 dollars per day
• D. 50 dollars per gigabyte

Correct answer: A

Rationale: The slope of the equation C = 50 + 75D is 75. This means that for each additional gigabyte used (represented by D), the cost (represented by C) increases by 75 dollars. Therefore, the correct interpretation of the slope is that it is 75 dollars per gigabyte. Choice B, 75 gigabytes per day, is incorrect as the slope does not represent the rate of data usage per day. Choice C, 50 dollars per day, is incorrect as it does not reflect the relationship between gigabytes used and the cost. Choice D, 50 dollars per gigabyte, is incorrect as it does not match the slope value of 75 in the equation.

3. Which type of waves require a medium (solid, liquid, or gas) to propagate?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: B

Rationale: Longitudinal waves require a medium (solid, liquid, or gas) to propagate because the particles in the medium move parallel to the direction of the wave. As a result, they rely on the medium for transmission. Transverse waves, on the contrary, do not need a medium and can travel through a vacuum, making choice A incorrect. Electromagnetic waves, represented by choice C, do not require a medium as they consist of oscillating electric and magnetic fields that can propagate through a vacuum. Surface waves, the option in D, involve a combination of both longitudinal and transverse motion and do require a medium to travel, but longitudinal waves are the ones that strictly depend on a medium for propagation.

4. Which of the following glands is NOT directly controlled by the pituitary gland?

• A. Thyroid gland
• B. Adrenal glands
• C. Pancreas (Islets of Langerhans)
• D. Parathyroid glands

Correct answer: C

Rationale: The pituitary gland, known as the master gland, regulates various endocrine glands by releasing specific hormones. The thyroid gland, adrenal glands, and parathyroid glands are directly controlled by the pituitary gland through hormones like thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), and parathyroid hormone (PTH) respectively. However, the pancreas, particularly the Islets of Langerhans, is not directly influenced by the pituitary gland. The pancreas is mainly governed by blood glucose levels and hormones such as insulin and glucagon, which play a crucial role in regulating blood sugar levels and metabolism. Therefore, the correct answer is C. Choice A, the thyroid gland, is controlled by the pituitary gland through TSH. Choice B, the adrenal glands, are regulated by the pituitary gland via ACTH. Choice D, the parathyroid glands, are under the direct control of the pituitary gland through PTH.

5. Which type of muscle is under voluntary control?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Involuntary muscle

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is under voluntary control, allowing for conscious movement of the body. Smooth muscle and cardiac muscle are both types of involuntary muscles that are not under conscious control. Smooth muscle is found in the walls of internal organs and blood vessels, functioning involuntarily. Cardiac muscle makes up the heart and contracts involuntarily to pump blood. Involuntary muscle (choice D) is a general term that encompasses smooth muscle and cardiac muscle, which operate involuntarily throughout the body.
