I don't believe that it would be very effective to just ban the advertisement.
I believe that simply banning the advertisement will not have much effect.
ご質問ありがとうございます。
① "I don't believe that it would be very effective to just ban the advertisement."=「単に広告を禁止するだけではあまり効果的ではないと私は思います。」
② "I believe that simply banning the advertisement will not have much effect."=「広告を単に禁止するのはあまり効果がないと思います。」
ご参考までに。
Just banning advertisement alone is not very effective
Banning advertisement alone
広告を禁止するだけ
この表現のaloneは、「〜だけ・〜しか何もしない」と言う意味で使われています。
Just banning advertisement alone is not very effective
単に広告を禁止するだけではあまり効果的ではありません
