why not A?
@gregmat if you please could walk me through this question, the dilemma here is that idiosyncrasy is a synonym for habit ( check the above page, google translate synonyms)
Hey Askan,
If you look at the grammar - the blank is an object noun for the subject noun- trips . Whereas habitually is an adjective for the subject - he .
I didn’t understand your clarification.
@gregmat in the video mentioned that the word in the blank must be a word that means habit that’s why he chose totality. My wonder is that idiosyncrasy also means habit. Moreover, it is noun.
