Question

Linking words
Marque a alternativa correta:
1. She was ..... unable to attend the meeting

a) in particular

b) therefore

c) as well as

Answer 1

She was, therefore, unable to attend the meeting.

That's the only linking word that works on the sentence, semantically. Just remember that, when used as an intensifier, therefore - as well as however, furthermore, and moreover - must be between commas.
