ルル

(1)③
has beenと受動態になっていることから選択肢の動詞の本来の目的語はconsiderable attentionだとわかります。pay attentionで注意を払うという意味なので③のpaid
(2)コンマ以前が「子供とその脳は長い間成長し続ける」となっています。その後は分詞構文を使って「次第に学んだり覚えたりする能力を〜しながら」となるので文脈からincreasingを入れて能力を高めながらとするのが一番文脈に合います
(3)be associated with のbeが分詞構文になっているbeingが正解
残り二つは入れたとしてどんな意味になるのかよく分かりません
