1. Assuming this statement is true, which of the answer choices is a logical conclusion?

• A. Whole language is more effective at teaching people to read than phonics.
• B. Phonics is more effective at teaching people to read than whole language.
• C. Literacy rates will probably continue to decline over the next 15 years.
• D. The definition of what it means to be literate is much stricter now.

Correct answer: B

Rationale: If we consider the information provided in the extract that literacy rates were higher when phonics was predominantly used and have declined since whole language programs became more popular, it logically follows that phonics is more effective at teaching people to read than whole language. Choice A is incorrect as the extract suggests the opposite. Choice C cannot be concluded based on the information provided; it is an assumption beyond the scope of the data. Choice D is also unrelated to the information given and does not logically follow from the provided statement.

2. A researcher wants to conduct qualitative research. Which method should they use?

• A. Collecting patient narratives
• B. Tracking the dosage of a drug and its blood levels in the patient
• C. Observing a patient's physical changes
• D. Writing journal notes about the research experience

Correct answer: A

Rationale: Qualitative research focuses on gathering non-numerical, descriptive data to explore experiences, behaviors, or perspectives. Collecting patient narratives aligns with qualitative research as it involves capturing detailed accounts of individuals' experiences or viewpoints. Choices B, C, and D involve more quantitative approaches by focusing on measurable quantities, observations, or structured note-taking, which are not characteristic of qualitative research methods.

3. A person wakes up with a fever. The body begins its response to locate the origin of the problem and fix it. What type of feedback mechanism is this?

• A. Equal
• B. Negative
• C. Neutral
• D. Positive

Correct answer: B

Rationale: This scenario describes a negative feedback mechanism. When the body detects a fever, it initiates responses to lower the temperature back to normal levels. Negative feedback mechanisms work to counteract changes and maintain homeostasis in the body. Choice A ('Equal') is incorrect as feedback mechanisms aim to restore balance, not maintain an equal state. Choice C ('Neutral') is incorrect as it does not describe the corrective nature of negative feedback. Choice D ('Positive') is incorrect as it would amplify the fever rather than regulate it.

4. What is the muscular sac that stores urine until it is released from the body known as?

• A. Urethra
• B. Bladder
• C. Ureter
• D. Nephron

Correct answer: B

Rationale: The bladder is the muscular sac that stores urine until it is released from the body. It acts as a reservoir for urine until it is eliminated through the urethra. The urethra is the tube responsible for carrying urine from the bladder to the outside. The ureter transports urine from the kidneys to the bladder. The nephron is the structural and functional unit of the kidney involved in the filtration of blood and urine production. Therefore, the correct answer is the bladder, as it specifically fulfills the function of storing urine before its elimination.

5. What phenomenon explains the formation of rainbows in the sky?

• A. Diffraction
• B. Interference
• C. Refraction and dispersion of sunlight by water droplets
• D. Reflection from clouds

Correct answer: C

Rationale: Rainbows are formed due to the refraction and dispersion of sunlight by water droplets in the atmosphere. When sunlight enters a water droplet, it is refracted, then internally reflected, and finally refracted again as it exits the droplet. This dispersion of light into its component colors creates the beautiful rainbow we see in the sky. Choice A, diffraction, involves bending of light around obstacles or through narrow openings, not the splitting of light into colors as seen in rainbows. Choice B, interference, refers to the phenomenon where two or more light waves overlap and interact, producing a pattern of light and dark bands, which is not the case with rainbows. Choice D, reflection from clouds, does not accurately describe the process involved in the formation of rainbows through refraction and dispersion of light by water droplets.
