Over two weeks of daily quizzes.
Hm, it would be nice to have more details. Do you have examples? Are those full tests or just a couple of questions? Are all level available every time, or do you send one at a time?
This is followed with a general explanation
This question asks you to select the phrase with the closest meaning to “脆い”, which best translates as “fragile”.
And a detailed explanation to why the choices were either correct or wrong.
The correct answer is 3. 壊れやすい。
“壊れる” means ”to break", and the stem of a verb + “やすい” means “easy to [do verb]”. So in this case, “壊れやすい” means “easy to break”, and so matches best with the meaning of “脆い”, (fragile).
This answer choice is not correct. “危ない” is an い-adjective that means “dangerous” (note: not to be confused with a negative verb as in “頼りない”) and so does not match the meaning of “脆い” (fragile).
This answer choice is not correct. “頼る” means “to depend on”, and the stem of a verb + “ない” creates the negative form of the verb. So in this case, “頼りない” means “not dependable”, which does not match the meaning of “脆い”, (fragile).
This answer choice is not correct. “辛い” is an い-adjective that when read “つらい” means “hard”, “tough”, “painful” (often in terms of mental pain or anguish), or alternately in a food context is read “からい” and means “spicy”, neither of which match the meaning of “脆い” (fragile).
