What work did Einstein do at the Swiss Patent Office?

Correct answer: Examining patents

The correct answer is C, examining patents. Einstein worked at the Swiss Patent Office in Bern, where he reviewed applications for inventions and assessed their technical ideas. This employment gave him a regular occupation while he continued thinking deeply about scientific problems in his own time. Writing stories, training soldiers, and painting pictures are unrelated to the work described in the chapter. The governing concept is distinguishing a patent examiner’s role from that of an inventor: Einstein evaluated technical proposals submitted by others rather than performing any of the activities in the other options. Remember the useful pair: Bern and Swiss Patent Office, with patent examination as his work.
