Question

choose the correct form of 1ts—with or without an apostrophe—for this sentence.
____ difficult even for native english speakers to understand middle english.
choose 1 answer:
a its
b its

Explanation:

The sentence needs a subject and verb to start the structure "____ difficult...". "It's" is a contraction of "It is", which functions as the subject and linking verb to introduce the adjective "difficult". "Its" is a possessive pronoun, which does not fit this grammatical structure.
