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 the sentence "I believe, therefore, that this is the best course of action", "therefore" is a conjunctive adverb used correctly to show a logical conclusion.
• For "Regular exercise makes you stronger; also, it helps you sleep", "also" is a conjunctive adverb and the semicolon - conjunctive adverb - comma structure is correct.
• For "Meanwhile, Cassie collected shells on the beach", "meanwhile" is a conjunctive adverb and its placement at the beginning of the sentence (with a comma) is correct.

The sentence "Declan wants to swim, instead Ellie wants to play tag" is incorrect. The correct structure for using "instead" as a conjunctive adverb would be "Declan wants to swim; instead, Ellie wants to play tag". The sentence "You should not sing in the concert if you have a cold, however" is incorrect. The correct structure would be "You should not sing in the concert if you have a cold; however," (if starting a new independent clause) or "However, you should not sing in the concert if you have a cold".

Answer:

• I believe, therefore, that this is the best course of action.
• Regular exercise makes you stronger; also, it helps you sleep.
• Meanwhile, Cassie collected shells on the beach.
