What is a central idea in Ronald Reagan's "First Inaugural Address"? The current times make it difficult to prosper in America. The people of the United States must put differences aside and work together as a team. The struggle ahead for America will be long and arduous. The government comprises people and as such must be respectful of all Americans.

The correct answer is: B) Phonemes.

A phoneme is defined as "the smallest unito of sound which is significant in a language". In this case, students are learning how vowels sound in French. It is clear every language has its own pronunciation, vowels won't saund the same in English as in French. So it is important to learn those differences to be able to undestand and speak a new language.

Syntax refers tp the structure or order of elements in a statement, so by learning the pronunciation of vowels it is not adressed.

Semantics is concerned with meaning of words or signs so it is not the correct answer.

Lastly morphemes refer to the smallest gramatical units in language, as students are not analyzing parts of an specific word or words this isn't the answer either.
