DIRECTIONS
1. Read the following sentence.
2. Follow the directions after the sentence.
3. Check your answer below.

Read this sentence:

FINISHED FILES ARE THE RESULT
OF YEARS OF SCIENTIFIC STUDY
COMBINED WITH THE EXPERIENCE OF YEARS.

Now count aloud the F's in that sentence. Count them ONLY ONCE; do not go back and count them again. 

There are 6 F's in the sentence.

One of average intelligence finds 3 of them.
If you spotted 4, you're above average.
If you got 5, you can turn your nose at most anybody.

If you caught 6, you are a genius.

There is no catch. Many people forget the OF's.
The human brain tends to see them as V's instead of F's.
