Question

Modern prosthetic technology has made remarkable advances in creating functional artificial thumbs for people who have lost theirs through injury or illness. Unlike older prosthetics that were rigid and immobile, today's artificial thumbs can bend, grip, and even sense pressure through electronic sensors. Some advanced models connect to remaining arm muscles and nerves, allowing users to control the prosthetic thumb simply by thinking about moving it. Users can perform surprisingly delicate tasks like typing, buttoning shirts, or holding a coffee cup. While prosthetic thumbs don't perfectly replicate natural thumb abilities, they restore enough function to dramatically improve daily life for users who previously struggled with one-handed tasks.

What is the main idea of this passage?

A

Prosthetic thumbs are now identical to natural thumbs in every way

B

Most people who lose a thumb choose not to get prosthetics because they're too expensive

C

Artificial thumbs work better than real thumbs for certain specialized tasks

D

Advanced prosthetic thumbs have greatly improved in functionality and can restore many daily abilities

Answer 1

D

The passage emphasizes that advanced prosthetic thumbs have greatly improved and can restore many daily abilities, whereas the other options are contradicted or not supported.
