Travel agents are market intermediaries who make their living by gather

Ing, organizing,and dispensing information about travel-related services

that is not readily available to most consumers through new information

technologies , such as the internet much of this information can now be

made directly available to consumers demand for the services of travel

agents will be drastically reduced

 

Which of the following ,if true , most seriously weakens the argument ?

 

1)            Travel agents routinely use the internet and other new information tech-

nologies as sources for the information they obtain for their customers .

2)            The amount of information available through the internet and other new

information technologies is increasing faster than the capabilities of

most consumers to process it

3)            Many people use travel-related services, such as airlines and hotels

without consulting a travel agent .

4)            The people who currently use the services of travel agents are also

those most likely to gain access to new information technologies

5)            The internet and other new information technologies are currently used

     by a relatively small proportion of the population

Last August the XT chain of gasoline stations had a temporary sales promotion in effect

In the promotion , any customer who made a purchase of ten or more gallons of gasoline

was entitled to a tree car wash . For the month of August , XT experienced a ten percent

increase in gasoline sales as compared to sales in August the previous year .so

evidently the promotion was successful as a means of boosting sales .

 

In evaluating the argument , it would be most helpful to answer which of the following ?

 

1)      In the areas in which XT’s gasoline stations operate , how did total combined

 gasoline sales for all gasoline stations last August compare with sales for the

 previous August?

2) Was the money that XT earned from the increase in gasoline sales enough to

 offset the cost of providing tree car washes during the promotion?

3) Were there any customers who bought ten or more gallons at an XT gasoline

  station during the promotion who would have or more gallons at an XT gasoline

in lower quantities , but more frequently ,if the promotion had not been in effect?

4)      Did XT or any or its gasoline stations have to pay other businesses to provide

   the car washes that customers were offered in the promotion?

5)      Are XT’s gasoline sales in August usually significantly higher than one twelfth of

XT’s annual gasoline sales ?

Several ancient Greek texts provide accounts of people being poisoned

By honey that texts suggest was made from the nectar of rhododen-

Dron or oleander plants. Honey made from such nectar can cause the

Effects the texts describe, but only if eaten fresh, since the honey loses

Its toxicity within a few weeks of being made. In Greece, rhododendrons

And oleander bloom only in springtime, when they are the predominant

Sources of nectar.

1)      There are no plants that Greece in ancient times that produce

more nectar than rhododendrons or oleanders do.

2)      In areas where neither rhododendrons nor oleanders grow, honey is

Never poisonous.

3)      A beebive’s honeycomb cannot have some sections that contain toxic

Honey and other sections that contain nontoxic honey

4)      The incidents of honey poisoning that are related in the ancient texts

Occurred in the sptingtime or in the earlysummer

5)      Whether the honey in a beehive is toxic depends solely on which plants

Were the source of that was used to make the honey.

I don't know what kind of this question. Maybe asking about which one to support.

My answer: D,A,E

GWD31说旅游中介是利用信息的不对称性来挣钱的(旅游中介有能力获取旅游景点的详细信息而游客却不能),然后说,互联网使信息的透明度增加,游客可以通过互联网来获得自己想知道的景点的消息,所以旅游中介的生意会大(注意这个大字)幅度下降.
E说,会使用互联网的人少.
故选E

第二题说,一个油站搞促销,买10加仑以上的油可以免费洗一次车,然后销量涨了10%.
促销是为了赚钱,如果多卖掉的汽油获得的收入大于洗车的成本,那就赚钱了.
B符合要求
