Question

CSI, standing for crime scene investigation, is an example of an acrostic.

Answer 1

The answer is  "False".

CSI, standing for crime scene investigation, is not an example of an acrostic. It is an example of "acronym".

Acronyms are just shortened forms made from the principal letter of each word in an expression or arrangement of words.  

An abbreviation is a word or name framed as a shortening from the underlying segments of an expression or a word, normally singular letters and sometimes syllables.  

An acrostic poem is where certain letters in each line spell out a word or expression. Commonly, the principal letters of each line are utilized to spell the message, however they can show up anyplace. A lyric where the principal letter of each line and the last letter of each line spell out words is known as a double acrostic.

Answer 2

It is not an acrostic.

CSI, standing for Crime Scene Investigation, is an example of an ACRONYM.

Acronym is a word formed from the initial letters of the words or phrase.

Acrostic is a poem or word puzzle wherein certain letters in each line form a word.
