Question

read the sentence.
having fallen out of the nest, the bird was insensible at first, but then flew off.
to decipher the meaning of the word insensible, break the word into
the root insens and the suffix -ible.
the root inseni and the suffix -ble.
the prefix in-, the root sens, and the suffix -ible.
the prefix insen-, the root eni, and the suffix -ble.

Explanation:

To determine the word parts of "insensible", we analyze word structure. The prefix "in - " means "not", the root "sens" relates to "sense" (like in "sensitive"), and the suffix "-ible" means "capable of". The other options have incorrect roots or prefix - root combinations. For example, "insens" or "inseni" are not valid roots, and "insen - " is not a correct prefix here. So the correct breakdown is the prefix in -, the root sens, and the suffix - ible.

Answer:

C. the prefix in-, the root sens, and the suffix -ible.
