Question

Sherman Poppen is credited with inventing the snowboard though many before him, including children and adults, have claimed to slide seamlessly down a hill while standing on a single flat surface, which allowed for the sport to take hold during the 1970s and 1980s.

How does the writer vary syntax in the sentence?

A. By separating a related idea using parentheses
B. By separating two dependent clauses with a comma
C. By using a comma splice for emphasis
D. By using a simple sentence structure

Answer 1

The correct answer is B. By separating two dependent clauses with a comma. In the sentence, the writer uses a comma to separate the dependent clause "including children and adults" from the independent clause "which allowed for the sport to take hold during the 1970s and 1980s."
