Welcome back to another TOEFL iTP podcast! This one features word-form problems and examples. Also, incorrect forms of words connected with certain fields. An example of this would be the confusion between biology and biologist — or between one of those terms and the adjectives that describes the field (biological). This is a follow up of the previous TOEFL practice I had already done, so make sure you tune into that.
The Black Hills of South Dakota are covered with densely pine forests.
The best answer is (D). An adjective, dense, not an adverb, is required to modify the noun phrase pine forests.
During solar storms, the amount of radiation reaching the Earth is abnormal high.
The adverb abnormally is needed to modify the adjective high.
First specializing in industrial photography, Margaret Bourke-White later became a famous news photographer and editorial.
The adjective editorial is used to describe the field of editing. However, a noun referring to a person (editor) is needed in this sentence.
Other Word-Form Problems

4. Bunsen burners are used to hot materials in a chemistry lab.

Rather than the gerund (-ing) form, the noun freeze is required.
