Help me with this exercise

Hi,

this exercise is in my Japanese textbook:

Ex: 日本 （交通が 便利です） → 日本に ついて ど う 思いますが。
.... ..交通が 便利だと 思います。

How do I apply the same to the following:

日本の 若い 人 （よく 遊びます）

？

I know for the question part, I can say

日本の 若い 人に ついて どう 思いますが。

But for the answer part, 遊びます is a verb, which is different from the adjective in the example. If I apply the grammar to the answer,

...よく 遊ぶと 思います。

I have no idea what the sentence means then. Please help if you have any idea. Thanks in advance.

よく 遊ぶと 思います
I think that Japanese youngsters frequently play. If you want the literal translation.
