Explanation: Choice B correctly uses 'three weeks'' with the apostrophe after 's' because 'weeks' is plural and the expression shows possession (time belonging to three weeks).

- The movie, that we watched last night was surprisingly entertaining and well-made.
Explanation: Choice C correctly uses commas to set off the nonrestrictive appositive 'Mrs. Johnson.' Choice A is missing a comma after 'Jake.' Choice B needs commas around 'Maya Angelou' if the speaker has only one author in mind, or no commas if specifying which author. Choice D incorrectly uses commas with a restrictive clause ('that we watched last night').

Choice A incorrectly uses 'teacher's' as if plural and 'student's' for multiple students (should be 'teachers' and 'students''). Choice C is missing an apostrophe entirely (should be 'companies''). Choice D should be 'women's' because 'women' is already plural, so the apostrophe goes before the 's'.
