My friend lives in Indiana.

His room is always gloomy, and it somehow makes me sad.

The birthrate in Japan is decreasing year by year.

We need to minimize the system's downtime.

My dream is to enter a national university.

He is an Indian and a very kind person.

In Japanese grammar, an autonomous forms the main part of the sentence.

He is acting based on his belief in the law of causality.

He stood straight, stretching his back.

His posture is always erect.
