Set 5: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 CRISPR is a revolutionary gene-editing tool that allows scientists to precisely cut and modify DNA. It holds the promise of curing genetic diseases like cystic fibrosis. Text 2 The ease and low cost of CRISPR raise bioethical concerns regarding 'germline editing'—changes made to embryos that are passed down to future generations. This could lead to 'designer babies' and irreversible alterations to the human gene pool.

What ethical dilemma does Text 2 introduce regarding the technology in Text 1?

A. The potential for eugenic applications and unintended long-term evolutionary consequences.✓ Correct
B. It is too expensive.
C. It does not work.
D. It only works on plants.

Detailed Explanation

Text 1: Cure diseases. Text 2: Germline editing/Passing down/Designer babies. Dilemma: Eugenic potential/Irreversible.

Key Evidence:

• "designer babies"

• "irreversible alterations"

• "gene pool"

Why others are wrong: B (Low cost.), C (Revolutionary.), D (Human gene pool.).
