皆英語は学校で習う為話せるが、日本語は話せる人が少ない。
Everyone can speak English since everyone learns English at school. But there aren't many people who can speak Japanese.
こういう訳で私はこのギャラリーの公用語を英語に、日本語は補助言語にするのを提案する。
For this reason, I suggest that we use English as an official language and Japanese as an auxiliary language of this gallery.
