Answer 1

Answer 2

The correct answer for this exercise is: c) Although flash mobs have been happening since 2003, lately, they have become a trend

Step-by-step explanation:

To understand the reason why c) is the correct option we need to analyze all of them.

However, we need to know first that complex sentences have a formula composition: an independent clause and one or more dependent clause. In other words, we will spot a rule of existence and then one or more consequences of that value "rule".

In a b and d cases, the independent clause is wrong because there is not a right condition or association followed by a dependent clause. We need something special to identify that there is going to be a change of idea and effect of the rule. In all these cases we declare that there is a rule but we don't have a proper construction of the phrase. Therefore, the dependent clauses are not properly written. The only C) case writes the independent clause correctly with its initial conditioning statement.
