Answer 1

The correct order of the statements is: d, b, a, c.

Answer 2

## Step 1The first step in the operation of an engine is the intake stage. During this stage, a mixture of air and fuel is drawn into the cylinder. This corresponds to statement d.## Step 2The second step is the compression stage. During this stage, the piston rises and compresses the fuel mixture in the combustion chamber. This corresponds to statement b.## Step 3The third step is the power stage. During this stage, the fuel mixture is ignited by the spark plug, and the resulting explosion forces the piston down in the cylinder. This corresponds to statement a.## Step 4The final step is the exhaust stage. During this stage, the exhaust gases left over from the combustion are released from the cylinder. This corresponds to statement c.
