質問: needについてるs teenagers should never be told that they will be taking the place of the parent who has died, rather you should help them focus on their needs for the future, such as education or training for work. however, again it is natural for the remaining members of the family to regroup and some sharing of responsibilities needs to take place. という少し長い分の最後の some sharing of responsibilities needs to take placeのresponsibilitiesにsがついてて複数なのにneedにsがついているのはどうしてでしょうか?だれか回答おねがいします。
回答: 主語部分は some sharing of responsibilities「責任の何らかの分担」です。some と of responsibilities は修飾部分なので中核は sharing で単数です。よって needs に呼応しています。 some は単数名詞にもかかります。
