Your question seems incomplete so i searched over internet and got the complete question which is:
"Larry is telling his sister about using a ruler to measure length. Fill in the blanks with ‘inch’ or ‘foot’ to make the sentence true.
1 __ is longer than 1 __. "
So basically we have to choose between "inch" and "foot" to decide which one is longer.
We know that 1 foot = 12 inches.
Which means 1 foot is longer than 1 inche.
Hence correct answer after filling the blanks will be:
1 FOOT is longer than 1 INCH.
