If the seventh day of a month is three days earlier than Friday, what day will it be on the nineteenth day of the month?
Answer: A
Correct answer: Sunday
Three days earlier than Friday is Tuesday, so the 7th is a Tuesday. The 19th is twelve days later, and \( 12 = 7 + 5 \), so it falls five days on from Tuesday - Sunday.

In a row of trees, one tree is fifth from either end of the row. How many trees are there in the row?
Answer: B
Correct answer: 9
The tree is counted from both ends, so the four trees before it and the four after it, together with the tree itself, make up the row: \[ 5 + 5 - 1 = \mathbf{9} \] The 1 is subtracted because the tree itself is counted twice.
