Set 4: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 Classical physics assumes time is a constant. A second on Earth is the same as a second anywhere else in the universe. Text 2 Einstein's Theory of Relativity rewrote this. It proved that time is relative; it slows down for objects moving at high speeds or in strong gravitational fields. This is known as time dilation.

How does Text 2 revise the concept presented in Text 1?

A. It replaces the notion of absolute time with a variable model dependent on speed and gravity.✓ Correct
B. It says time does not exist.
C. It proves clocks are broken.
D. It says time speeds up.

Detailed Explanation

Text 1: Time = Constant (Absolute). Text 2: Time = Relative/Variable/Dilation. Revision: Absolute -> Variable.

Key Evidence:

• "assumes time is a constant"

• "relative"

• "slows down ... variable"

Why others are wrong: B (Relative.), C (Physics.), D (Text says slows down.).
