解説

C Q1 take measures
"take measures" = 措置を取る。take action も同様。

B Q2 make an impact
"make an impact" が固定コロケーション

B Q3 sign agreements
"sign agreements" = 協定に署名する

B Q4 do research / conduct research
"do research" も正しい("conduct" がより formal)

C Q5 have an effect
"have an effect on" が正しい前置詞コロケーション

B Q6 The number of... → has
核が "number"(単数)なので has

B Q7 more cleaner → cleaner
比較級の二重表現は誤り

B Q8 must to invest → must invest
法助動詞の後は動詞原形

B Q9 each of → has
"Each" は常に単数扱い

B Q10 since → for
"since" は起点 / "for" は期間

B Q11 mitigate = reduce
"mitigate" = 軽減する(アカデミック語)

C Q12 collaborate = work together
"collaborate" = 協力する

B Q13 substantial = significant
"substantial" = かなりの・相当な

C Q14 sustainable = able to continue long-term
"sustainable" = 持続可能な

B Q15 curb = restrict
"curb" = 抑制する・制限する
