They provide background information to help the reader understand events.

Explanation:

Flashbacks talk about a previous event, meaning they can explain the current situation in some way, shape, or form, be it how a friend was made or why so-and-so hates bars.

However, internal conflicts could be a good second answer as it could answer the question of why this is such a big deal (I.E. why being forced to throw out a rose when it was touched by a crush during a herbology lesson or something is something the protagonist doesn't want to do despite the fact it's been dead for weeks, though, again gives context for why said rose is important).

in "people in peace, not profit and war" chrisholm uses inductive reasoning for her argument against defense spending by stating that the new administration, like most americans, wanted to invest in social objectives, so they must not want to prioritize defense spending. mr. nixon said "we can delay no longer in launching new approaches to the problem that beset them", but chrisholm points out that the programs were delayed anyways.

a complex sentence consists of an independent clause and one or more dependent clauses.  

to write complex sentences, we must use subordinating conjunctions.  

all the complex sentences begin with a subordinating conjunction and when it occurs, a comma must be place at the end of the dependent clause. on the contrary, if the sentence begins with an independent clause, then no comma is used.
