Question

which simple machines make up scissors?
two inclined planes and two wedges
two levers and two wedges
one lever and two wedges
one inclined plane and two wedges

Explanation:

Scissors consist of two levers (the handles and blades act as levers with the pivot as the fulcrum) and two wedges (the sharp blades are wedges used for cutting). The other options are incorrect: inclined planes don't fit scissors' structure, and the number of levers is two (not one) as scissors have two arms acting as levers.

Answer:

B. two levers and two wedges (Note: Assuming the second option is labeled B; if the original options had labels like A, B, etc., adjust accordingly. Here, the second option is "two levers and two wedges".)
