Question

which sentences use conjunctive adverbs correctly? check all that apply. i believe, therefore, that this is the best course of action. declan wants to swim, instead ellie wants to play tag. regular exercise makes you stronger; also, it helps you sleep. you should not sing in the concert if you have a cold, however. meanwhile, cassie collected shells on the beach.

Explanation:

• For "I believe, therefore, that this is the best course of action":
• The conjunctive adverb "therefore" is used to show a logical conclusion. It is placed correctly within the sentence to connect the thought "I believe" with the conclusion "this is the best course of action".
• For "Regular exercise makes you stronger; also, it helps you sleep":
• The conjunctive adverb "also" is used to add another related point. The semicolon before "also" correctly separates the two independent clauses, and "also" is used appropriately to show an additional benefit of regular exercise.
• For "Meanwhile, Cassie collected shells on the beach":
• The conjunctive adverb "Meanwhile" is used to show an action happening at the same time as another (implied). It is placed at the beginning of the sentence correctly to introduce the concurrent action.

• For "Declan wants to swim, instead Ellie wants to play tag":
• The correct usage for "instead" as a conjunctive adverb requires a semicolon before it (e.g., "Declan wants to swim; instead, Ellie wants to play tag"). The comma here is incorrect.
• For "You should not sing in the concert if you have a cold, however":
• The conjunctive adverb "however" is usually placed either at the beginning of a new sentence (with a comma) or after a semicolon in a compound - sentence. Placing it at the end of the sentence as here is incorrect.
