Critical Reasoning

hi,

give me your thoughts on this.......

Q-A new recycling plant is so efficient that it can recycle any kind of non-toxic material. However, when transporting items to the recycling room, the conveyor belt intermittently stops, and then, a moment later, resumes its movement. Perhaps it is getting old and needs to be replaced; but an alternative hypothesis is that while constantly moving, the conveyor belt requires large amounts of electricity to run, and so short pauses allow the plant to save energy.

Which of the following, if discovered regarding the recycling plant, would support one of the two hypotheses and undermine the other?

A. When the conveyor belt was first installed in the recycling plant, it did not pause as frequently as it does now.

B. The intermittent pauses of the conveyor belt are not related to the types of materials transported by the belt.

C. The conveyor belt was recently installed to take advantage of technology that would reduce the resources required to move material around the plant.

D. If, when the belt pauses, the weight distribution of material on the belt suddenly changes, the belt does not resume movement as quickly as when the weight distribution remains the same.

E. Advances in energy-saving technology no longer require that conveyor belts periodically stop to conserve energy.

OA C

Option C

Reason -
The conveyor belt was recently installed undermines the hypothesis that the belt is old. And the following piece supports the other hypothesis that it was installed with the intention to reduce electricity usage - "would reduce the resources required to move material around the plant"

wud go for C
