"with the timing contingent on the actual transmission of its past policy actions to lending rates and incoming data, particularly on upside risks to inflation."

what does this sentence mean please explain in simple English 😛 😛

People's television-viewing habits could be monitored by having television sets, when on, send out low-level electromagnetic waves that are reflected back to the sets. The reflected waves could then be analyzed to determine how many persons are within the viewing area of the sets. Critics fear adverse health effects of such a monitoring system, but a proponent responds, "The average dose of radiation is less than one chest x-ray. As they watch, viewers won't feel a thing."


Which of the following issues would it be most important to resolve in evaluating the dispute concerning the health effects of the proposed system?

The price the government pays for standard weapons purchased from military contractors is determined by a pricing method called "historical costing." Historical costing allows contractors to protect their profits by adding a percentage increase, based on the current rate of inflation, to the previous year's contractual price.

Which of the following statements, if true, is the best basis for a criticism of historical costing as an economically sound pricing method for military contracts?


Patrick usually provides child care for six children. Parents leave their children at Patrick's house in the morning
and pick them up after work. At the end of each workweek, the parents pay Patrick at an hourly rate for the child
care provided that week. The weekly income Patrick receives is usually adequate but not always uniform,
particularly in the winter, when children are likely to get sick and be unpredictably absent.

Which of the following plans, if put into effect, has the best prospect of making Patrick's weekly income both
uniform and adequate?

A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.

The researcher’s conclusion depends on which of the following assumptions?

The blue-tipped Puffer is a migratory bird that is found along the coast of this state in summer months.  The Puffers enjoy the seeds of Thomson’s Mulberry trees; because these trees are plentiful in the state’s Coastal Park, traditionally many blue-tipped puffers would be found in the park during summer months.  Ten years ago, the grey fox, a primary predator of the Puffer, was re-introduced into the park, and their number have been thriving.  Over that time, we have seen many fewer Puffers in the park during the summer months.  Clearly, the Puffers are choosing to spend their summers elsewhere.

Which of the following would be the most important to determine in order to evaluate the argument?



The director of programming at NNN, the National News Network, proclaimed that, despite charges to the contrary, the Network does not have a conservative bias. The director acknowledged that, when a liberal news personality was recently added to the Network, an additional conservative news program was also established. However, the director argued that far from demonstrating any bias, these actions reflect a commitment to presenting a balanced perspective in interpreting current events. Which of the following pieces of information would be most useful in evaluating the validity of the programming director’s argument?

Calories consumed in excess of those with which the body needs to be provided to maintain its weight are normally stored as fat and the body gains weight. Alcoholic beverages are laden with calories. However, those people who regularly drink two or three alcoholic beverages a day and thereby exceed the caloric intake necessary to maintain their weight do not in general gain weight. 


Which one of the following, if true, most helps to resolve the apparent discrepancy?

(A)

Some people who regularly drink two or three alcoholic beverages a day avoid exceeding the caloric intake necessary to maintain their weight by decreasing caloric intake from other sources.

(B)

Excess calories consumed by people who regularly drink two or three alcoholic beverages a day tend to be dissipated as heat.

(C)

Some people who do not drink alcoholic beverages but who eat high-caloric foods do not gain weight.

(D)

Many people who regularly drink more than three alcoholic beverages a day do not gain weight.

(E)

Some people who take in fewer calories than are normally necessary to maintain their weight do not lose weight.

Psychiatrist: We are learning that neurochemical imbalances can cause behavior ranging from extreme mental illness to less serious but irritating behavior such as obsessive fantasizing, petulance, or embarrassment. These findings will promote compassion and tolerance when looking at a mental illness, quirk, or mere difference between two persons, since being mentally healthy can now begin to be seen as simply having the same neurochemical balances as most people.

Which one of the following most accurately expresses the conclusion of the psychiatrist's argument?

The Habitat Conservation Plan (HCP) is based on a law that allows developers to use land inhabited by endangered species in exchange for a promise to preserve critical habitat or provide replacement land nearby. Some individuals of endangered species are lost in return for assurances by the owner or developer that habitat for those remaining animals will be protected. Environmentalists are pleased that HCPs allowed them to win concessions from developers who would otherwise ignore rarely enforced environmental laws. Satisfied property owners prefer HCPs to more restrictive prohibitions of land use.

The situation described above most closely conforms to which one of the following principles?

Drinking Roost, a children's health drink, must be a good habit. This substantially increases the stamina and IQ required by children for winning competitive cricket matches. Interviews conducted with young cricketers who drank one cup of Roost each before and after the match, confirmed that the players were feeling much fresher than those who did not take the health drink

What is the principal flaw in the above reasoning?

In the past 50 years, the population of honeybees in the United States has been cut in half. The decline is due primarily to the increasing use of pesticides in the United States, as well as to the introduction of two types of mites that weaken and kill the bees. Honeybees are the primary pollinators for a variety of important fruit crops, including oranges, apples, grapes, peaches, cranberries and watermelons. Therefore, if the honey bee population continues this drastic decline, then most fruits will no longer be available to consumers.

In evaluating the conclusion, which of the following questions would be LEAST useful to answer?

A Are there other insect pollinators that could pollinate these fruit crops instead of the honeybee?
B Are honeybee populations declining in other important fruit-producing regions, like Chile and New Zealand?
C Is it feasible for humans to hand-pollinate the fruits that have been pollinated by bees?
D Will reducing the use of pesticides in the United States reverse the decline in honeybee populations?
E Is it possible to genetically engineer fruit-producing plants so that they no longer require pollination?

If, in a tennis tournament, a match reaches a fifth-set tiebreak, the lower-ranked player always loses the tiebreak (and, therefore, the match). If Rafael, the second-ranked player, wins a tournament by beating Roger, the topranked player, then the match must not have included a fifth-set tiebreak. Which of the following arguments most closely mimics the reasoning used in the above argument?

Recently, a plane crashed near the outskirts of Berlin within minutes after its takeoff from Berlin airport. Initial analysis confirmed that the crash was caused by either the usage of substandard fuel or a fault in the control board. Since the airport staff tested the control board before the plane took off, analysts hypothesize that the reason behind the plane crash was substandard fuel.


Which of the following options, if true, most strengthens the analysts’ hypothesis?

Some psychologists attribute complex reasoning ability to reptiles, claiming that simple stimulus-response explanations of some reptiles' behaviors, such as food gathering, cannot account for the complexity of such behavior. But since experiments show that reptiles are incapable of making major alterations in their behavior, for example, when faced with significant changes in their environment, these animals must be incapable of complex reasoning. 
Which one of the following is an assumption required by Sylvia's argument?

(A) Animals could make major changes in their behavior only if they were capable of complex reasoning.
(B) Simple stimulus-response explanations can in principle account for all reptile behaviors.
(C) Reptile behavior appears more complex in the field than laboratory experiments reveal it to be.
(D) If reptiles were capable of complex reasoning, they would sometimes be able to make major changes in their behavior.
(E) Complex reasoning and responses to stimuli cannot both contribute to the same behavior

Agricultural societies cannot exist without staple crops. Several food plants, such as kola and 
okra, are known to have been domesticated in western Africa, but they are all supplemental, 
not staple, foods. All the recorded staple crops grown in western Africa were introduced from 
elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering 
when rice and yams were introduced into western Africa would establish the earliest date at 
which agricultural societies could have arisen there. Which of the following is an 
assumption on which the argument depends? 
A. People in western Africa did not develop staple crops that they stopped cultivating once rice 
and yams were introduced. 
B. There are no plants native to western Africa that, if domesticated, could serve as staple food 
crops. 
C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of 
western Africa. 
D. Kola and okra are better suited to growing conditions in western Africa than domesticated 
rice and yams are. 
E. Kola and okra were domesticated in western Africa before rice and yams were introduced 
there.

Cézanne’s art inspired the next generation of artists, twentieth-century modernist creators of abstract art. While most experts rank Cézanne as an early modernist, a small few reject this idea. Françoise Cachin, for example, bluntly states that such an ascription is “overplayed,” and says that Cézanne’s work is “too often observed from a modern point of view.” Which one of the following statements is most strongly supported by the information above?

  • Cézanne’s work is highly controversial.
  • Cézanne was an early creator of abstract art.
  • Cézanne’s work helped to develop modernism.
  • Cézanne’s work tends to be misinterpreted as modernist.
  • Modern art owes less to Cézanne than many experts believe.

A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors, 33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not. The conclusion drawn above depends on which of the following assumptions?
