Question

read this text.
crater lake in oregon was formed by mount mazama, a volcano that erupted, collapsed, and filled with rainwater more than seven thousand years ago.
is this an appropriate use of an ellipsis?
\crater lake in oregon was formed by mount mazama, a volcano that erupted... more than seven thousand years ago.\
yes
no, because the text with an ellipsis no longer has the same meaning

Explanation:

An ellipsis is used to indicate an omission. In the original text, the volcano "erupted, collapsed, and filled with rainwater". The ellipsis in "erupted...more than seven thousand years ago" removes "collapsed, and filled with rainwater", changing the meaning of how Crater Lake was formed.

Answer:

no, because the text with an ellipsis no longer has the same meaning
