Explanation:

1. Question 12: This tests correct punctuation for compound/related clauses. Option F uses an unnecessary semicolon before "and". Option H lacks a comma before the coordinating conjunction "but" joining two independent clauses. Option J uses a colon incorrectly (it should be a semicolon or period). Option G correctly uses a comma before "but" to separate two independent clauses.
2. Question 13: This tests direct quotation punctuation. Option B omits a comma after "said" before the quote. Option C incorrectly uses a comma before the quote with "suggested that". Option D misuses quotation marks with an indirect question structure. Option A correctly places a comma before the opening quotation marks and ends the quote with proper punctuation inside the marks.
3. Question 14: This tests punctuation for appositives, lists, and clauses. Option F has a misplaced appositive with incorrect punctuation (needs a comma after "told"). Option G uses a semicolon incorrectly instead of a comma. Option H lacks commas to separate parallel activities ("growing roses, weaving, and volunteering"). Option J correctly uses a colon to introduce a list of specific activities.
