Ken is my best friend.

I am raising funds to start a new business.

There are keys in my pocket.

In his room, a Nazi swastika flag was hung.

My younger brother is diligently practicing Taekwondo every day.

He is studying seriously.

His research made a significant contribution to the scientific community.

I practice Tai Chi in the park every morning.

My hometown is Fukui Prefecture.

He is conducting research on a new energy source.
