Welcome to the Voice of America's "News Words," where we teach you about words in the news.
This word is from a story about the U.S.government gathering telephone and Internet records:The basic questions are these:
Is the surveillance relevant to a terrorist investigation? And does the government monitor actual conversations and emails
or just look at who's involved? "Investigation" means to examine something closely and carefully. In this story,the government
is directing the investigation to find terrorists. Police,as well as scientists and other people,carry out investigations to
learn about events and how they happen.
Now,when you hear the word "investigation,"your English will be good enough to know what this News Word means.
