A. finishing nails.
B. corrugated fasteners.
C. #10 screws.
D. glue.

Back 15

B. corrugated fasteners.
B. Corrugated fasteners (one is shown below) are probably best to use to repair split wood, since they draw the edges of the wood together. A #10 screw would be too big. Nails and glue don't really support the corners.

Back 17

A. plumber.
A. The large jaws and heavier weight of a monkey wrench are ideal for loosening and tightening large nuts and bolts that are usually encountered by plumbers. While it is possible for other workers to use a monkey wrench, the question uses the word ?usually,? suggesting that one type of person would be more likely than the others to use the wrench. Read the questions carefully for clues.
