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 6
Multiple Choice Question
Question
Experiment 2: A researcher compares three insulating materials. Identical cups receive equal volumes of water initially at 80°C. One cup is wrapped in cotton, one in foam, and one in aluminum foil.
