1. Which statement about the following set is true? {60, 5, 18, 20, 37, 37, 11, 90, 72}

• A. The median and the mean are equal.
• B. The mean is less than the mode.
• C. The mode is greater than the median.
• D. The median is less than the mean.

Correct answer: D

Rationale: To find the median, we first need to arrange the set in ascending order: {5, 11, 18, 20, 37, 37, 60, 72, 90}. The median is the middle value, which is 37 in this case. The mean is calculated by adding all numbers and dividing by the total count, which gives a mean greater than 37. Therefore, the statement that the median is less than the mean is correct. Choice A is incorrect because the median and mean are not equal in this set. Choice B is incorrect as the mean is greater than the mode in this set. Choice C is incorrect as the mode is 37, which is equal to the median, not greater.

2. Archie says, 'Northerners eat bland food.' The most precise definition of this statement is

• A. A stereotype
• B. An inference
• C. A bias
• D. A generalization

Correct answer: A

Rationale: The correct answer is A: a stereotype. Archie's statement about Northerners eating bland food reflects a stereotype, which is an oversimplified and generalized belief about a particular group of people. This statement is not an inference because it is not based on evidence or reasoning. It is also not a bias, which is a preference or inclination that inhibits impartial judgment. While the statement could be seen as a generalization, it more specifically fits the definition of a stereotype due to its oversimplified and exaggerated nature.

3. Which of the following suffixes has an action that means 'relating to'?

• A. -ic
• B. -ology
• C. -ation
• D. -ate

Correct answer: A

Rationale: The correct answer is '-ic.' The suffix '-ic' means 'relating to,' as seen in words like 'artistic' (relating to art). - 'B' is incorrect as the suffix '-ology' refers to the study of a subject, not 'relating to.' - 'C' is incorrect as the suffix '-ation' is used to form nouns expressing an action or process, not 'relating to.' - 'D' is incorrect as the suffix '-ate' is used to form verbs or nouns denoting an office, function, or rank, not 'relating to.'

4. Which lifestyle practice can benefit the lymphatic system?

• A. Consuming a high-sugar diet
• B. Maintaining a sedentary lifestyle
• C. Regularly engaging in moderate exercise
• D. Smoking cigarettes

Correct answer: C

Rationale: Regularly engaging in moderate exercise benefits the lymphatic system by promoting circulation and aiding in the removal of toxins and waste products from the body. This helps maintain a healthy lymphatic system. Consuming a high-sugar diet can lead to inflammation and hinder lymphatic function. Maintaining a sedentary lifestyle can result in poor circulation, which negatively affects the lymphatic system. Smoking cigarettes introduces toxins into the body, further burdening the lymphatic system. Therefore, the correct lifestyle practice that can benefit the lymphatic system is regularly engaging in moderate exercise.

5. Which of the following is the main organ responsible for regulating sleep?

• A. Thalamus
• B. Hypothalamus
• C. Pituitary gland
• D. Pineal gland

Correct answer: B

Rationale: The main organ responsible for regulating sleep is the hypothalamus. The hypothalamus plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. It receives input from the eyes about light and darkness, aiding in determining when it's time to sleep or wake up. Additionally, the hypothalamus regulates the production of melatonin by the pineal gland, a hormone that helps control sleep patterns. While the thalamus relays sensory information to the brain, the pituitary gland is primarily responsible for hormone production and release, and the pineal gland produces melatonin under the control of the hypothalamus. Therefore, the hypothalamus is the correct choice as the main organ involved in sleep regulation.
