请各位高手看看: 3 CRs that I can't find answers

They are from TTGWD 31 (verbal.doc???) but no answers to them:

1. The cause of the wreck of the ship Edmund Fitzgeraid in a severe storm

on lake Superior is still unknown , when the sunken wreckage of the ves-

sel was round , searchers discovered the hull in two pieces lying close

together , The storm’s violent waves would have caused separate pieces

floating even briefly on the surface to drift apart . Therefore . the breakup

of the null can be ruled out as the cause of the sinking .

Which of the following is an assumption on which the argument dipends?

1) Ships as large as the Edmund Fitzgerald rarely sink except in the

most violent weather.

2) Under water currents at the time of the storm did not move the sepa-

rated pieces of the hull together again.

         3) Pieces of the hull would have sunk more quickly than the intact hull

would have

4) The waves of the storm were not violent enough to have caused the

5) If the ship broke up before sinking , the pieces of the hull would not

have remained on the surface for very long

2. 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

3. 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.

What’s the question?

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.
