Definition: Rewrite each original sentence in order to make it easier to understand by non-native speakers of English. You can do so by replacing complex words with simpler synonyms (i.e. paraphrasing), deleting unimportant information (i.e. compression), and/or splitting a long complex sentence into several simpler ones. The final simplified sentences need to be grammatical, fluent, and retain the main ideas of their original counterparts without altering their meanings.
Input: Following the murder of Van Gogh, tens of thousands gathered in the center of Amsterdam to mourn Van Gogh's death.

When Van Gogh was murdered, tens of thousands gathered in the center of Amsterdam to mourn him.
