The history of the development of the computer mouse is long and complex, but it was Douglas Engelbart who is credited with creating the first working prototype in 1964. Engelbart's invention was a revolutionary concept in the field of human-computer interaction, one that would change the way people interact with technology forever. His invention was a small wooden box with two metal wheels that could be moved across a flat surface, and it allowed users to control the cursor on a computer screen by rolling the box. The mouse's invention had a profound impact on the development of computers and the world, and it is still used by millions of people every day.
","stem_html":"Which choice provides the best revision of the underlined portion of the passage?
","rationale_html":"The underlined portion is in the past tense, so the verb should also be in the past tense. The past tense verb "was credited" correctly reflects the past tense of the rest of the sentence. Choice B is incorrect because the verb is in the present tense, which doesn't match the tense of the rest of the sentence. Choice C is incorrect because the verb "has been credited" is in the present perfect tense. Choice D is incorrect because the verb "was being credited" is in the past progressive tense.
