The answer is A. Mercedes threw Andrea, Mercedes' best friend, a surprise party last night. This choice uses an appositive ("Andrea, Mercedes' best friend,") to combine the two sentences. An appositive is a phrase separated from the rest of the sentence by commas that describes something (in this case Andrea).
Choices B and C are incorrect because the uses of the words "but" and "when" to combine the sentences do not make logical sense. Choice D is incorrect because it uses a comma to combine the sentences without a conjunction, creating a run-on sentence.
Hope this helps!
Ok I learn about this before so it means to be ambitious or to I really forgot but along those lines ro be hopeful
Answer:
The data watchdogs clampdown on social media goes further than MPs expected and is only part of a much bigger counter-attack. It was anticipated that the draft guidelines from the Information Commissioner´s Office would deal with the gathering and management of children's data, and they would demand that companies collect the absolute minimum of information in line with teenagers´ welfare and security.
Explanation:
Apostrophes in English are most commonly used for contractions.
However, there´s also the possessive apostrophe which shows possession by adding 's to a noun (Commissioner´s Office).
If the noun in case ends in s, wether is singular or plural, the possession is shown by adding an apostrophe after the s (teenagers´ welfare).
