The correct answer is A) coal deposits.
During the Late Carboniferous, Indiana lay close to the equator, making the climate humid and warm. Swamps and wetlands were prominent in much of the state. Dominant fossil plants from this time include lycopods, conifers, and seed ferns (extinct gymnosperms). Plant material accumulated in these areas of Indiana and eventually became the source of Indiana’s abundant coal deposits.
During this time, rivers drained the remnants of the Acadian mountain. Large amounts of sand stayed on the banks of the rivers. Scientists and archeologists working in the zone have found fossils of bryozoans, crinoids, gastropods, and brachiopods. There many carboniferous rocks in the southwestern territories of Indiana.

Explanation:
It is impossible for the student to interpret a correct conclusion about his experiment, without adding a control treatment where he can really compare the differences between the variables.

In the case of the question above, it would have been necessary for the student to have placed a cart on a ramp of normal height and without sandpaper. That way he could compare the speed between this cart and the carts on the other ramps, thus having a correct result.
