Confusion about implementing math strat. in this question

can we use math strategy in this one?
I am confused if we can use “opposition” as contrast word and go forward with math Strat. somehow. Although, block of 4 and just semantics make more sense but I am just curious if math Strat is viable here.

Are you talking about the second blank?

Yep, you can even use the word “between” as a contrast word as well.
