Question

which is the best way to complete the text?
now that theyve retired, my grandparents spend most weekends volunteering for local ______ hosting dinner parties at their lake home.
charities, or
charities. or
charities; or
charities or

Explanation:

This question tests correct punctuation for parallel phrases. The two activities ("volunteering for local charities" and "hosting dinner parties") are parallel elements in the sentence. When separating two parallel independent phrases in this structure, we use a comma before the coordinating conjunction "or". A period would incorrectly split the sentence into two incomplete thoughts, and a semicolon is unnecessary here as the phrases are not independent clauses. Omitting the comma creates a run-on structure for the parallel items.

Answer:

charities, or
