1. Jeff needed a 6 ft. rope. He found 2 pieces of rope and thought maybe he could tie them together. One rope was 40 inches and the other was 36 inches. How long would the rope be, and would he have enough rope if he ties them together?

• A. No, the rope would be 76 inches.
• B. Yes, the rope would be 76 inches.
• C. Yes, the rope would be 6 feet.
• D. No, the rope would be 6 feet.

Correct answer: B

Rationale: To convert 6 feet to inches, we multiply 6 by 12 (1 foot = 12 inches), giving us 72 inches needed. By adding the lengths of the two ropes (40 inches + 36 inches), Jeff would have a total of 76 inches, which is more than the 72 inches required. Therefore, he would have enough rope if he ties them together. Choice A and D are incorrect because they misinterpret the conversion from feet to inches. Choice C is incorrect as it does not consider the actual combined length of the two ropes.

2. What word is best to substitute for the underlined words in the following sentence? Stu often regarded his roommates’ housekeeping as sloppy and careless.

• A. his
• B. hers
• C. them
• D. their

Correct answer: D

Rationale: The word 'their' is the best substitute for the underlined words in the sentence because it refers to Stu's roommates in a possessive form, indicating that the housekeeping belongs to them. 'His' (Choice A) refers to Stu, not the roommates. 'Hers' (Choice B) is incorrect as it refers to a female possessive form. 'Them' (Choice C) is a pronoun for a group of people but does not show possession, making it unsuitable in this context.

3. Which organ system is primarily responsible for regulating muscle growth?

• A. The skeletal system
• B. The endocrine system
• C. The nervous system
• D. The reproductive system

Correct answer: B

Rationale: The endocrine system is primarily responsible for regulating muscle growth through the production and release of hormones such as growth hormone, testosterone, and insulin-like growth factors. These hormones play crucial roles in stimulating muscle protein synthesis, increasing muscle mass, and promoting overall muscle growth and repair. The skeletal system provides structural support for muscles but does not directly regulate muscle growth. The nervous system controls muscle contractions and movements but is not primarily responsible for muscle growth. The reproductive system plays a role in fertility and secondary sexual characteristics but does not have a direct role in regulating muscle growth.

4. Which molecule is primarily responsible for storing energy in cells?

• A. Glucose
• B. ATP
• C. Fatty acids
• D. Starch

Correct answer: B

Rationale: ATP is the correct answer because it is the molecule responsible for storing and providing energy in cells. Glucose is a source of energy but not primarily for storage. Fatty acids are more involved in energy production through oxidation. Starch is a polysaccharide used for energy storage in plants.

5. A wave in a rope travels at 12 m/s and has a wavelength of 2 m. What is the frequency?

• A. 38.4 Hz
• B. 6 Hz
• C. 4.6 Hz
• D. 3.75 Hz

Correct answer: B

Rationale: The frequency of a wave is calculated using the formula: frequency = speed / wavelength. In this case, the speed of the wave is 12 m/s and the wavelength is 2 m. Therefore, the frequency is calculated as 12 m/s / 2 m = 6 Hz. Choice A (38.4 Hz), Choice C (4.6 Hz), and Choice D (3.75 Hz) are incorrect as they do not result from the correct calculation using the given values.
