Question

look at the text below. if there is an error with subject - verb agreement, select the incorrect verb and type it correctly. otherwise, submit the text without making any changes. though most electronics are engineered to be rigid and durable, some is purposely designed to disintegrate and dissolve, such as those used in certain medical implants.

Explanation:

The subject "some" here refers to "some electronics" (since the context is about electronics). "Electronics" in this context is a plural noun (referring to electronic devices or components), so the verb should agree with a plural subject. The incorrect verb is "is"; it should be "are" to match the plural subject.

Answer:

The incorrect verb is "is", the correct verb is "are". The corrected sentence: Though most electronics are engineered to be rigid and durable, some are purposely designed to disintegrate and dissolve, such as those used in certain medical implants.
