1. When water boils, it changes from a liquid to a gas. This is an example of a:

• A. Chemical reaction
• B. Physical change
• C. Nuclear reaction
• D. Biological process

Correct answer: B

Rationale: This is a physical change because boiling water involves a change in state from liquid to gas without altering the chemical composition of the water molecules. In a chemical reaction, new substances are formed by breaking and forming chemical bonds, which is not the case during boiling. A nuclear reaction involves changes in atomic nuclei, which are not occurring during boiling. A biological process refers to activities related to living organisms, which is not applicable to the change from liquid to gas in boiling water.

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

• A. Liver
• B. Kidneys
• C. Pancreas
• D. Heart

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.

3. Which word completes the sentence 'He was ____ by the unexpected turn of events.'?

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: In the sentence, 'He was bewildered by the unexpected turn of events,' the word 'bewildered' means confused, which is the most suitable choice to convey the feeling caused by unexpected events. 'Elated' means joyful, 'vindicated' means justified, and 'apathetic' means uninterested, making them less fitting in the context of being surprised or thrown off by unexpected events.

4. University Q has an extremely competitive nursing program. Historically, 3/4 of the students in each incoming class major in nursing, but only 1/5 of those who major in nursing complete the program. If this year’s incoming class has 100 students, how many will complete the nursing program?

• A. 75
• B. 20
• C. 15
• D. 5

Correct answer: C

Rationale: Out of the 100 students, 3/4 major in nursing, which equals 75 students. However, only 1/5 of these 75 students will complete the program. Calculating 1/5 of 75 gives us 15 students who will complete the nursing program. Therefore, the correct answer is 15. Choice A (75) is incorrect as it represents the total number of students majoring in nursing, not completing the program. Choices B (20) and D (5) are incorrect calculations and do not align with the information provided in the question.

5. Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

• A. frontal lobe
• B. occipital lobe
• C. parietal lobe
• D. temporal lobe

Correct answer: C

Rationale: The parietal lobe is the correct answer because it is primarily responsible for processing and integrating sensory information received from the rest of the body, including touch, pressure, temperature, and pain. This lobe plays a crucial role in spatial awareness, perception, and attention to sensory stimuli. It helps individuals make sense of the world around them and is essential for various sensory processes. The frontal lobe (choice A) is more associated with functions like reasoning, planning, and problem-solving. The occipital lobe (choice B) is responsible for processing visual information. The temporal lobe (choice D) is involved in functions like memory, auditory processing, and language comprehension, but it is not the primary lobe responsible for processing and integrating sensory information from the body.
