________________________________
CR 1 Along the mudflats of Garantia, exist two types of annelids: earthworms and lugworms. Earthworms tend to emerge from the mud early in the morning when there is more moisture and nutrients. As a result, earthworms have access to more nutrients and thus reproduce far faster than the lugworm, which spends much of the day submerged in the mud. Nonetheless, the lugworm population far outnumbers that of the earthworm.
Which of the following, if true, helps LEAST to resolve the apparent discrepancy noted above?
(A) Lugworms have specialized taste receivers, which allow them to access nutrients below ground far more easily than earthworms can.
(B) The whooping crane, the earthworm’s chief predator, hunts along the mudflats during the time the earthworms are feeding at the surface.
(C ) Lugworms resemble the color of the mudflat, and are thus more difficult to spot by predators than earthworms are.
(D) Compared to the lugworm, earthworms are able to consume fewer nutrients at one time.
(E) Lugworms tends to emerge in the evening, when the number of predators is less than during the early morning hours, when the earthworm is exposed on the mudflat.

CR 2GPS, the Global Positioning System (GPS) is a global navigation satellite system and is often used for navigating by car. Traveler's Best Friend (TBF) is a new navigation aids company which believes that not only drivers but also hikers could use GPS for navigating and have therefore decided to develop a GPS device for hikers.
Which of the following, if true, most seriously strengthens TBF's conclusion?
A. Technical problems prevent the entry of old mine fields data into the GPS device program.
B. A survey conducted by TBF shows that 82% of hikers would buy GPS hardware and software if the price is manageable.
C. Due to high developing prices, the price for the end purchaser is estimated at $15,000, far more expensive than any other single hiking accessory.
D. A rival company, TBP (traveler's best pal) has tried to develop the device, but were forced to halt the development due to technological limitations.
E. The estimated weight of the GPS system is roughly 40 pounds.
