My boyfriend gave me a gift.

Everyone was surprised by the news.

I took a course in quantitative analysis at university.

We conducted a volumetric analysis for this project.

He is an expert in chemical analysis.

A new approach is needed to solve this set of problems.

The main problem with this project is the lack of communication.

This question text is too difficult, it's hard to understand.

This exam is a matter of life or death for me.

He is viewing that situation as a serious problem.
