Problem: Scientists studied two island. One with an old ecosystem named Old island, and the other with a newly formed and forming ecosystem named New island. Both islands were inhabited, Old island being heavily inhabited.  Given the paragraph above, please answer correctly the following question:   Which island had a more favorable amount of rainfall for new ecosystems?

A: New


Problem: Two scientists went to Antarctica for research. Tim was assigned to East Antarctica, while John was assigned to West Antarctica. They spent 6 months there.  Given the paragraph above, please answer correctly the following question:   Which scientist experienced fewer weather fronts?

A: John


Problem: The underwater fishing teams picked their spots early. Team Bob went at the mouth of the river, where the freshwater met the salty seawater in the hope that more turbidity from the river and more nutrients will attract more fish. Team Dan went south where they knew there was less of a thermocline, so they could catch fish without taking risks.  Given the paragraph above, please answer correctly the following question:   Which team had their crew members to fewer risks than necessary?

A: Dan


Problem: Dan studied genetic engineering. He was applying his knowledge of genetic engineering to develop better crops. Recently, he had successfully developed a crop, crop A, that was herbicide tolerant. To determine the versatility of the crop he compared it with another crop that was not tolerant of herbicides, crop B. The results of his research would allow his company to market the new crop.  Given the paragraph above, please answer correctly the following question:   Which crop would be less beneficial to farmers, crop A or crop B?

A:
crop B
