Answer:
A.
Explanation:
This phenomenon best illustrates why intelligence tests need to be revised for predictive validity. The tests are taken initially and show high scores, then they are taken again and show even higher scores. This shows that the individuals are getting smarter. If the test continues to be taken without revision then the same results will continue since the individuals will continue to become smarter but the test will continue being the same. Therefore, becoming much easier for the participants every time. This ultimately leads to better and better scores.
The answer would be: Intake, Compression, Power, and Exhaust.
<span>Intake: also known as induction or suction.
Compression: starts at the end of the suction stroke, and ends at T.D.C.
<span>Power: also known as combustion. This is the start of the second revolution of the four stroke cycle.
</span><span>Exhaust: also known as outlet. In here, the piston once again returns from B.D.C. to T.D.C. while the exhaust valve is open. This action eliminates the spent air-fuel mixture through the exhaust valve.</span></span>
