Nit Picking

Postby jpSartre » Mon Mar 15, 2010 2:25 pm

38, 4, 6

Lactose, a sugar found in milk, aids in the absorption of calcium, which in turn is required for bone repair. in addition to there being shortages of milk in tropical areas, inhabitants of these areas lose the ability to absorb lactose, unlike people form nontropical areas. Yet inhabitants of tropical areas have no more problems with bone repair than do people who inhabit tropical areas

Resolve the paradox

B) milk consumption has fallen in both tropical and nontropical areas

C) the abundant sunlight in tropical areas causes the human body to produce vitamin D naturally, which aids in the absorption of calcium

C is obviously a good answer, but at the same time in B) the drop in milk consumption doesn't matter for people in tropical areas because they cant absorb lactose anyway, and if milk consumption has decreased in nontropical areas to the point where people are having problems with bone repair equal to the problems people are having in tropical areas due to the inability to absorb lactose (i.e. people in nontropical areas don't drink milk at all), couldn't B be right?

Is the lesson here that decreased means a depletion to a number above zero?

I think the lesson is that falling consumption doesn't necessarily mean zero consumption, or even consumption equal to that of tropical areas (notice they don't say no one in a tropical area gets their calcium from milk). The crux is just finding which answer explains the difference; thus, falling consumption in both areas doesn't differentiate the two enough to explain the paradox. C, however, does.

Right I see what you're saying. B could resolve the paradox, but C definitely does.

Stimulus wants you to resolve the same effect with a different cause in tropical areas.

Key: cause/effect question. Find the missing cause which is sunlight.

UConn is going to take it
