Lexical Resource（語彙力）評価について

解説

A Q1 provides evidence
"provides evidence" が正しいコロケーション。"gives evidence" も使えるが provides がより academic。

C Q2 take action
"take action" が固定表現。do action / make action は不正解。

C Q3 significant impact
"significant / major impact" がアカデミックで自然。"big/large impact" は非アカデミック。

B Q4 reach a conclusion
"reach a conclusion" が正しいコロケーション。

D Q5 draw/bring attention
"draw attention to" / "bring attention to" どちらも正解。

A Q6 The number of... → is
"The number of ～" は単数扱い（核は "number"）

B Q7 Despite of → Despite
"despite" は前置詞なので "of" は不要

B Q8 researches → research
"research" は不可算名詞

A Q9 suggested to revise → suggested revising
"suggest" は動名詞（V-ing）を目的語にとる

B Q10 recently years → recent years
"recent" は形容詞。"recently" は副詞。また現在完了が必要。

A Q11 implement（動詞）
"implement new policies" が正しいコロケーション

C Q12 increase（名詞）
"a significant increase in..." が標準表現

B Q13 accidental discovery
"accidental" = 偶然の（形容詞）

B Q14 essential for
"essential for" が正しい前置詞コロケーション

A Q15 development
"development of technology" が名詞形
