CR Questions May - 14 :CR Questions May - 15 :Q1. In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle populations, even though they seldom burrow.
Which of the following, if true, most helps to explain the surprising finding?
(A) Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.
(B) Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest.
(C) The strength of the tidal currents in a given location varies widely over the course of a day.
(D) A very large barnacle population can significantly decrease the ability of a horseshoe crab to find food.
(E) Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.

Q2. Political Commentator: During the previous presidential administration, members of congress approved large tax cuts and yet the economy today stands in shambles. During the current economic crisis, those who espouse large tax cuts as an economic stimulus should consider the failure of tax cuts during the past eight years to prevent the current economic recession as conclusive evidence that tax cuts will not help the country escape from its current economic troubles.
Which of the following, if true, most weakens the argument above?
(A) The large tax cuts of the past administration targeted the capital gains on the financial investments of the ultra-rich while proponents of tax cuts today suggest cutting payroll taxes for both employers and employees.
(B) Economists from across the spectrum now agree that tax cuts helped stem the country’s most severe recession in history, which occurred about 70 years ago prior to industrialization in this country.
(C) Economists from across the spectrum predict that if Congress fails to pass the tax-cut legislation, which also includes government spending and much more, it could well be 15 years before the economy escapes the current recession.
(D) Economists from across the spectrum agree that these tax cuts will add less to the fiscal deficit than the tax cuts of the previous administration.
(E) During the most recent political campaign cycle, which featured many deceptive political attacks, the governor of a prosperous state attacked those who opposed tax cuts by citing his own state’s ostensible prosperity.
