Explanation:

Question 4

• Option A: A hypothesis is a proposed explanation for an observation, which is testable.
• Option B: A hypothesis is not a random guess; it's based on observations and reasoning.
• Option C: The portion for comparison is the control group, not a hypothesis.
• Option D: The details of an experiment are the experimental procedure, not a hypothesis.

So, option A is correct.

The scientific process starts with observing a phenomenon, then forming a hypothesis (a possible explanation), testing the hypothesis (via experiments), analyzing the data from tests, and finally drawing conclusions.

• Option A: Skips the initial observation step.
• Option B: Follows observe → hypothesize → test → analyze → conclude, which is the correct scientific method sequence.
• Option C: "Question" is not the standard step; the correct step after observation is hypothesizing.
• Option D: Skips observation and has a repeated (typo - same as A) incorrect sequence.

So, option B is correct.

Answer:

A. a possible explanation of an observation.
