Question

select the word or phrase that is redundant and can be removed without changing the meaning of the text. despite the fact that the hindenburg was filled with seven million cubic feet of highly flammable and combustible hydrogen gas, the german airship had a smoking lounge.

Explanation:

"Flammable" and "combustible" have very similar meanings. Using both is redundant as one alone can convey the property of the hydrogen gas being able to catch fire. Removing one (either "flammable" or "combustible") won't change the overall meaning of the sentence.

Answer:

Either "flammable" or "combustible" (since they are redundant as they mean nearly the same thing regarding the property of catching fire for the hydrogen gas).
