John is a geologist. He was trying to figure out how the Earth's inner core is made. To that end, he compared earth's physical characteristics to available items. First he took a sample of surface rock, which he labeled as item B. Then he took a sphere of constant density, which he labeled as item C. Finally, he labeled the Earth as item A.  Given the paragraph above, please answer correctly the following question:   Would item A have higher or lower moment of inertia than item C?
Ans: lower

Given the paragraph above, please answer correctly the following question:   In which country resource use would most likely outpace ecosystem sustainability?
Ans: Qatar

Mike is studying for his physics exam. He realizes that the best way to learn physics is to solve problems. To that end, he needs to to convert pressure of objects from one unit to another. In one problem, four scenarios are given for the same object, scenario A, scenario B, scenario C, and scenario D. In scenario A the pressure is given in Pascals. In scenario B the pressure is given in the atm. In scenario C the pressure is given in torr. Lastly, in scenario D the pressure is given in psi.  Given the paragraph above, please answer correctly the following question:   In which scenario mercury may not be a factor in devising the unit, scenario A or scenario C?
Ans: scenario A

Greg is an electrical engineer. He works for an engineering firm that builds houses. Yesterday, Greg was checking two of the houses. He noticed that one of the houses had short circuit. He labeled that as case A. But the other house didn't have short circuit. He labeled that as case B.  Given the paragraph above, please answer correctly the following question:   Would case B see less or more resistance cut out than case A?
