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:

The words "flammable" and "combustible" have very similar meanings. Both describe the property of being able to catch fire easily. Using both is redundant as one word alone can convey the same idea about the hydrogen gas.

Answer:

"combustible"
