Problem 11 - Entrance Test

The scientist hypothesized that the newly discovered element would exhibit unique properties due to its unusual atomic structure. After conducting a series of experiments, she found that the element _______ reacted with water, _______ confirming her initial predictions.

Correct: A

The correct answer is 'violently; thereby'. The adverb 'violently' describes how the element reacted. 'Thereby' indicates the cause of the confirmation. The adjective 'violent' is not grammatically correct. 'Thus' can work, but thereby is more clear as it directly states how the capturing is being performed.
