Question

select the clickable phrase from paragraph 11 that provides a clue for the meaning of the word regularity. the following day, the program repeated what had been studied previously. of course, it was possible to switch subjects around somewhat to take arithmetic before history, or, in place of one rule of grammar, to take another. but these were small changes that didn’t really matter, so nothing ever really happened to disrupt the regularity of the lessons.

Explanation:

To find the clue for "regularity", we analyze the paragraph. The text says the program repeated what was studied before, and small changes didn't disrupt the regularity. The phrase "repeated what had been studied previously" shows a pattern or regularity in the lessons, as repeating previous study implies a consistent, regular structure. Also, "small changes that didn't really matter" contrasts with the idea of regularity, but the key clue is the repetition of study, and the clickable phrase (from the context of the question, likely the relevant phrase in the paragraph) that clues "regularity" is related to the consistent, repeated nature. Looking at the paragraph, the phrase "repeated what had been studied previously" provides the clue as it shows the regular, repeated pattern of the lessons, which relates to "regularity" (the quality of being regular, consistent).

Answer:

repeated what had been studied previously
