Question

1. from the passage, which two ideas show how roots and prefixes affect word meaning? roots give the main idea of a word. prefixes can change the meaning while keeping the root’s idea. roots and prefixes always make words longer. prefixes remove meaning from the root.

Explanation:

Roots are the core of a word, carrying its main meaning. Prefixes are added to roots and can modify the meaning while still relating to the root - concept. For example, "un -" as a prefix can change the meaning of a root word like "happy" to "unhappy". The third option about length is not related to meaning. The fourth option is incorrect as prefixes usually add or change meaning rather than remove it.

Answer:

Roots give the main idea of a word.
Prefixes can change the meaning while keeping the root’s idea.
