The futures market lets investors speculate on future products before they are produced. If a poor pork bellies supply is expected later, pork bellies’ futures prices rise; if a bountiful pork bellies supply is expected, pork bellies futures prices fall. This morning, swineologists predicted an oncoming influx of much-needed slop in the pigpen regions starting tomorrow. Thus, since sufficient slop is essential for the survival of a strong current supply of fuller pork bellies, prices of pork bellies futures will decline dramatically today.
Which of the following, if true, most weakens the argument to the left?
A. Pigs that do not consume adequate slop during the critical growth stage will not produce a full, rich product.
B. This fiscal year, pork bellies futures prices have varied more erratically compared to last year.
C. The slop that swineologists predict for tomorrow is only expected to be distributed well outside the pigpen areas.
D. Today, a press release by pork experts said that the foot-in-mouth disease decimating some of the pork bellies supply will spread widely before the start of the slaughtering season.
E. Investors who speculate in pork bellies futures rarely take physical possession of the pork bellies they trade.
P1: The futures market lets investors speculate on future products before they are produced.
P2: If a poor pork bellies supply is expected later, pork bellies futures prices rise.
P3: If a bountiful pork bellies supply is expected, pork bellies futures prices fall.
P4: This morning, swineologists predicted an oncoming influx of much-needed slop in the pigpen regions starting tomorrow.
P5: Sufficient slop is essential for the survival of a strong current supply of fuller pork bellies.
C1: Prices of pork bellies futures will decline dramatically today.
A)
INCORRECT. This strengthens the argument because it confirms P4 and P5. The argument is based on the fact that a strong supply of slop results in fuller (heavier) pork bellies. This answer states that "pigs that do not consume adequate slop will not produce a full, rich product". This is consistent with the argument.
B)
INCORRECT. This strengthens the argument because it confirms P4 and P5. The argument is based on the fact that a strong supply of slop results in fuller (heavier) pork bellies. This answer states that "pigs that do not consume adequate slop will not produce a full, rich product". This is consistent with the argument.
C)
INCORRECT. First off, the pigpen is where the pork bellies (pigs) live. This answer would appear to imply that the slop will not be distributed to the pigs. IMO there is not enough information for us to make this jump.
D)
Correct!. This answer states that a "disease that is decimating some of the pork bellies supply will spread widely before the start of the slaughtering season". If the disease spreads "widely" and more pork bellies die before the start of the slaughtering season then the supply for this year's harvest will go down. Per premise P2, a drop in supply will result in a rise in prices. This is counter to the conclusion of the argument that "prices of pork bellies futures will decline dramatically today".
E)
INCORRECT. This answer is not relevant to the argument. The conclusion is that "prices of pork bellies futures will decline dramatically today". Whether investors in the futures market take physical possession of the pork bellies does not affect the price of pork bellies. This answer has no affect on the conclusion.
