My boyfriend gave me a gift.

Everyone was surprised by the news.

He loves physics and studies it in the library almost every day.

I am majoring in physical chemistry at university.

He is a world-famous physicist.

It is reported that North Korea has conducted another nuclear bomb test.

He is looking for a proving ground to test his new theory.

These test results are showing unexpected outcomes.

We analyzed the data of the experimental group.

He has a deep interest in empirical science.
