1. What defines a proper fraction versus an improper fraction?

Correct answer: A

Rationale: A proper fraction is characterized by having a numerator smaller than the denominator, while an improper fraction has a numerator larger than the denominator. Therefore, choice A is correct. Choice B is incorrect because it states the opposite relationship between the numerator and denominator for proper and improper fractions. Choice C is incorrect as it describes a fraction where the numerator is equal to the denominator, which is a different concept. Choice D is incorrect as it associates a numerator being smaller than the denominator with an improper fraction, which is inaccurate.

2. Which of the following is a logical conclusion that can be derived from the announcement above?

Correct answer: C

Rationale: The logical conclusion that can be derived from the announcement is that the library has added the fee to discourage patrons from spending too long on the computers. This conclusion is supported by the fact that the library is limiting computer usage to 30 minutes and implementing a fee for extended use. Choice A is incorrect because there is no indication in the announcement that the library plans to purchase more computers. Choice B is incorrect as there is no mention of budget cuts or using the fee to compensate for them in the announcement. Choice D is incorrect as there is no information in the announcement about the library covering its Internet service costs by passing on the fee to patrons.

3. What is the technical term for the involuntary muscular contractions that move food through the digestive tract?

Correct answer: B

Rationale: Peristalsis is the term used to describe the involuntary muscular contractions that move food through the digestive tract. This process involves rhythmic contractions and relaxations of the muscles in the digestive system, which help propel food from the esophagus to the stomach and through the intestines for digestion and absorption of nutrients. Segmentation refers to the mixing movements in the intestines that aid in the absorption of nutrients but is not the term for the movement of food through the digestive tract. Chylification is not a recognized term in digestive physiology. Emulsification is the process of breaking down fat globules into smaller droplets to aid in digestion, not the movement of food through the digestive tract.

4. Which structure controls the hormones secreted by the pituitary gland?

Correct answer: A

Rationale: The correct answer is A: Hypothalamus. The hypothalamus controls the release of hormones from the pituitary gland. It acts as a master regulator of the endocrine system by producing releasing and inhibiting hormones that influence the secretion of hormones from the pituitary gland. Choice B, the Adrenal gland, is incorrect because while it plays a role in hormone production, it is not responsible for controlling the pituitary gland's hormones. Choice C, the Testes, and Choice D, the Pancreas, are also incorrect as they are not directly involved in controlling the hormones secreted by the pituitary gland.

5. Which of the following organs is responsible for filtering waste from the blood?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.
