Solve this faster with the right shortcut first
Shortcut used: Identify the hypothesis, changed variable, measured outcome, controls, and evidence before answering.
Solve in 3 steps:
- Identify the first relation/pattern.
- Apply the same rule to the missing part.
- Reject options that break the rule.
Common mistake: Do not pick a merely related option; it must match the exact pattern.
Question 3
Multiple Choice Question
Question
Experiment 1: A student tests whether salt concentration affects radish-seed germination. Four groups of 30 seeds receive equal volumes of solutions containing 0%, 1%, 2%, or 3% salt. All groups use the same seed source, containers, light, and temperature. After seven days, the student records the percentage of seeds that germinated.
Which result would best support the hypothesis that increasing salt concentration reduces germination?
Explanation
Correct Answer: C
ANSWER
Correct Answer: C
Method / Topic: Scientific Reasoning
A consistent decline as salt increases matches the proposed negative effect.
Why this answer is correct
The correct option preserves the same pattern.
Short Explanation
A consistent decline as salt increases matches the proposed negative effect.
