Technology is rapidly expanding the scope of capabilities for both professional and personal use; such is the case with smart phones. Professionals now have devices available to them capable of digital media, internet access, phone communication, multi-person scheduling and office tools for documents and presentations. Business people that are often mobile may maximize the use of these critical features on smart phones. Individuals who simply enjoy the luxury of multi-function devices often use these devices for frivolous pursuits such as downloading catchy ring tones, instant messaging about the latest gossip and looking up the world record for most cans crushed on one's head during the Superbowl. This fusion of capabilities and increased availability of such devices could be a sign of a growing blend in society between work and personal life, or individuals could simply be taking a luxurious approach to their connectivity in personal lives.   What is the purpose of the conclusion sentence?

A. draw a conclusion about what we know smart phones can do

B. present two possible explanations for the growing popularity of smart phones

C. comment on human connectivity through the use of smart phones

D. predict how the government will regulate and guide future technology

Answer Explanation:

The conclusion statement gives two possible explanations of the growing popularity of smart phones i.e., could be a sign of a growing blend in society between work and personal life, or individuals could simply be taking a luxurious approach to their connectivity in personal lives.

Therefore, the Correct Answer is B.

Q #1: Delaying their initial entry to school can cause some children to actually fall behind their peers in learning. Some studies have shown differing early childhood academic achievement results when comparing children from low-income families with those living in middle-income homes Children from low- income homes tend to begin school with weaker skills than their peers from more advantaged backgrounds. Holding young children back a year before they begin their academic career is sometimes thought to help them mature before beginning school. This practice may actually backfire for some of those children from low-income households. During the additional year at home, these children are thought to miss opportunities to cultivate the basic skills that they could develop while taking part in a learning environment-skills suggested to be absent in some low-income families.   Consider a revision which replaces the terms low-income and middle-income with the terms poor and normal. What effect would this change have on the passage?

A. It would make the passage more specific

B. It would make the passage inaccurate

C. It would make the passage less academic

D. It would make the passage biased.

Answer Explanation

It makes it inaccurate since low income is not synonymous to abnormal and middle income is not synonymous to normal.
Q #2: Disequilibrium at the interface of water and air is a factor on which the transfer of heat and water vapor from the ocean to the air depends. The air within about a millimeter of the water is almost saturated with water vapor and the temperature of the air is close to that of the surface water. Irrespective of how small these differences might be, they are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water vapor content. The turbulence, which takes its energy from the wind mixes the air. As the speed of wind increases, so does the turbulence, and consequently the rate of heat and moisture transfer. We can arrive at a detailed understanding of this phenomenon after further study. The transfer of momentum from wind to water, which occurs when waves are formed is an interacting-and complicated phenomenon. When waves are made by the wind, it transfers important amounts of energy-energy, which is consequently not available for the production of turbulence. The wind over the ocean usually does which of the following according to the given passage I. Leads to cool, dry air coming in proximity with the ocean surface. II. Maintains a steady rate of heat and moisture transfer between the ocean and the air. III. Results in frequent changes in the ocean surface temperature.

A. I only

B. II only

C. I and II only

D. I, II, and III

Answer Explanation

The air within about a millimeter of the water is almost saturated with water vapor and the temperature of the air is close to that of the surface water. Irrespective of how small these differences might be, they are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water vapor content. The turbulence, which takes its energy from the wind mixes the air. As the speed of wind increases, so does the turbulence, and consequently the rate of heat and moisture transfer.
Q #3: Which of the following is an example of a secondary source?

A. The notes of a doctor who practiced during an influenza epidemic

B. Journal entries of a patient who spent two weeks quarantined during an influenza outbreak

C. A textbook summarizing eyewitness accounts of an influenza epidemic

D. Photographs in a museum exhibit about a world famous influenza outbreak

Answer Explanation

A secondary source of information is one that was created later by someone who did not experience first-hand or participate in the events or conditions you are researching. They include scholarly books and articles.
