Set 5: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 Vaccines stimulate the specific immune system (antibodies). They provide long-term memory against a pathogen. Text 2 The innate immune system is the body's first line of defense. It includes skin, mucus, and inflammation. Unlike the specific system, it is non-specific and has no memory.

Based on the texts, how do the two immune systems differ?

A. The specific system adapts and remembers, while the innate system is a generalized barrier.✓ Correct
B. The innate system is slower.
C. Vaccines work on the innate system.
D. They are the same.

Detailed Explanation

Specific (Vaccines): Memory/Targeted. Innate: First line/Non-specific/No memory. Difference: Adaptation/Memory vs Generalized.

Key Evidence:

• "long-term memory"

• "non-specific and has no memory"

Why others are wrong: B (First line (Initial).), C (Stimulate specific.), D (Different.).
