an obstruction in a blood vessel is called a[n] _______, but if you exaggerate, or "throw" the meaning of something too far, then you have used a[n] ______.

Answer 1

An obstruction in a blood vessel is called a[n] stroke, but if you exaggerate, or "throw" the meaning of something too far, then you have used a strike.

"Stroke" is the correct answer for the first blank, since strokes occur when there is an obstruction in a blood vessel supplying blood to the brain.
"Strike" is the correct answer for the second blank since "strike" is a verb (action) which means to throw something forcefully in an exaggerated manner.
