Professor: One expert on Norse culture argues that since yarn (fiber thread) samples discovered at non-Norse archaeological sites, those related to the aboriginal Dorset people in the East Arctic, are similar to prehistoric Norse yarn samples, and since spinning was not a part of the technology of northern aboriginal peoples, the Dorset samples constitute proof of contact between these aboriginal people and Norse Vikings. The fact that radiocarbon dating seems to indicate that the Dorset samples predate Norse arrival in the region by centuries is dismissed by the expert as an anomaly attributable to significant problems with the dating of textiles found at Arctic sites. But this position seems questionable, given that
Which of the following would, if true, most logically complete the professor's argument above?

Many large stone heads have been discovered in what was once Olmec territory in Mesoamerica and have facial features similar to those found among people in certain parts of Africa, but it does not necessarily suggest that the founders of Olmec civilization came directly from Africa, since many indigenous peoples of countries such as Cambodia and the Philippines have similar characteristics.
Subjects asked to make which of the following predictions would be most likely to commit the fallacy discussed in the passage (if the claims of the passage are correct)?
Government regulations in Nation X require that milk products labeled "organic" come from cows that have access to pasture. Many industrial dairies have begun using the organic label on their products even though their cows spend most of their milk-bearing lives confined to feed lots eating grain. Critics charge that industrial dairy cows spend too little time grazing in pastures for their milk to bear the organic label, but the cows' owners insist that the animals are in good health and show no signs of discontent.
Which of the following would it be most useful to establish in order to determine whether the industrial dairies' use of the organic label complies with government regulations?
Many oppose the national economic planning program that the government is Initiating because they fear that It will Impair the ability of corporations to make rational economic choices. But that program will never work anyway. There Is no reason, therefore, to expect the negative effect those people fear.

Archaeologists have excavated two ancient sites, Site A and Site B, each containing bowls and dishes. A third site containing similar vessels (bowls and dishes), Site C, Is known to have existed but has not yet been located. The vessels have been dated to three successive 40-vear-long time periods (Mil).
The dishes that were found are small and plain and were made primarily for everyday use. For each site, the average population at the site for a period is known to be roughly proportional to the number of dishes found that were dated to that period.
The bowls are more elaborate, decorated In either a curvy or a rectilinear style. They were made primarily for ritual use. The numbers of bowls found indicate the level of wealth of the site's inhabitants during the period to which the bowls were dated (with greater numbers indicating greater wealth).
Documents found at Sites A and B establish that exactly 18 of the dishes found at Site A were manufactured at Site C; otherwise, all of the vessels were made at the sites where they were found.
For each of Sites A through C, select Yes If the Information provided Indicates that the population at that site was both greater in Period II than Period I and greater in Period III than in Period II. Otherwise, select No.

Because of the positive correlation across animal species between body size and home range size, researchers suspected that body size of female mallards (a species of duck) may influence their home range size. The researchers also reasoned that younger females may be forced into less suitable habitats by older females competing with them for optimal areas, with the younger females compensating by having larger home ranges. However, their research supported neither suspicion. The failure to detect variation of range size according to body size may be due to other, undetermined mallard attributes (for example, body condition) that may have been a significant factor affecting home range size. The fact that most yearling females can breed may help to explain why the expected age effect was not confirmed, since home range size may be affected by breeding capability.
The researchers did find, however, that home range size of females was Inversely related to the percentage of the study area composed of seasonal or semipermanent wetlands. This may have been because of reduced competition for breeding space within the species when more of the wetlands were present. They also found home range size to decrease somewhat as the percentage of wood-shrub habitat increased, suggesting that reduction in visual contact among mallard pairs may reduce interaction and thus reduce competition among breeding pairs.
The author's purpose in making the statement that most yearling female mallards are able to breed is most likely in order to
In 90 percent of the commercial airline accidents last year, one or another of a group consisting of only 18 percent of the world's commercial airlines was involved. Since the other 82 percent of airlines were generally flying the same types of airplanes as the accident-prone airlines, significant differences in safety procedures must have been responsible for these differences In safety records.
Which of the following, if true about the world's commercial airlines last year, most seriously weakens the argument above?

Welleby’s Plan
The water In the underground water table beneath the town of Welleby is moderately saline— 20,000millkjrarns of salt per liter of water (mg/L), or roughly half as saline as ocean water. To lower the level of the water table and thus prevent agricultural land from being inundated with salt water, the town plans to pump water from the table at a rate of 450kiloliters per day (kL/day) into a large shallow pond, allowing much of the water to evaporate. The town plans to divert 10percent of the water pumped from the water table to supplement Us supply of drinking water, which Is currently piped In from great distances. Due to the water's supply, the town intends to construct a desalination plant to treat the diverted water for use as drinking water.
Desalination Types
Comparison
Welleby is deciding among the following three desalination methods.
Reverse Osmosis (RO): Water Is pushed through a membrane, leaving salts behind. RO systems can handle a large range of water flow rates and use relatively little energy. However, RO membranes are expensive and must be replaced every 2 to 5 years. There is also a possibility that bacteria can grow on the membrane. Introducing tastes and odors Into the desalinated water.
Multi-Effect Distillation (MED): Saline water Is heated to produce water vapor, from which Is condensed potable fresh water. This process requires large amounts of energy, regardless of the salinity of the source water. It becomes more cost effective as water volumes increase.
Electrodialysis (ED): Electricity is used to selectively move salts through a membrane. Consumption of energy Is directly proportional to the salinity of the water to be treated, so with higher salinities the process rapidly becomes more costly than other methods. ED membranes need to be replaced every 7 to 10years.
Based on the information provided, which one of the following benefits to Welleby is most likely to result from Its building a desalination plant?

West River Glen is deciding which network architecture should replace its old copper telephone lines. The town will replace 300 miles of Outside Plant (OSP) cable that will serve approximately 2,500 homes.
The first option is to install a Fiber to the Home (FTTH) system architecture that uses fiber-optic cable to transmit signals from the source to each home. The advantages of this architecture include greater bandwidth capabilities, less signal loss, and slightly lower new-cable deployment costs than the second option, Hybrid Fiber-Coax (HFC).
An HFC network integrates fiber-optic cables and devices with coaxial cables.
This will cost the town substantially less money for internal equipment and for customer installations. However, the coaxial cable does not last as long as fiberoptic cable and will thus need to be replaced more frequently, resulting in higher long-term maintenance expenses.
The town believes that either the FTTH or HFC architectures will be capable of serving the communities' data and television needs for the next 30 years.
For each of the following statements, select Yes if the statement can be inferred to be true on the basis of the information provided. Otherwise, select No.

It is known from cave paintings and other evidence that the hunting people occupying the Bax Cave area in Country X tens of thousands of years ago repeatedly set fire to
the surrounding area. Archaeologists hypothesize that because the fires caused later plant growth on the land, the hunters set the fires in order to attract herbivorous prey
species. Such actions, they claim, are evidence for the mental capacity to delay gratification for weeks, months, or even years.
