D in most books flashbacks are used in a lot of different forms
A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.
There are three conjunctions in this sentence: neither, nor, and because.
Given that neither and nor are not subordinating, the correct answer would be the word because. The reason for this is because it connects the independent clause (Neither Laura nor I will attend the concert) with the dependent/subordinate one (because you cannot go).
