GWD-24-16

    

which of the
following most logically completes the argument below?

    

According to
promotional material published by the city of Springfield,
more tourists stay in hotels in Springfield than
stay in the neighboring city of Harristown.
A brochure from the largest hotel in Harristown claims that more tourists stay
in that hotel than stay in the Royal Arms Hotel in Springfield. If both of these sources are
accurate, however, the “Report on Tourism” for the region must be in error in
stating that   .

    

1. the average length of stay is longer
        at the largest hotel in Harristown than it is at the Royal Arms Hotel.
2. There is only one hotel in Harristown
        that is larger than the Royal Arms Hotel.
3. More tourists stay in hotels in
        Harristown than stay in the Royal Arms Hotel.
4. The Royal Arms hotel is the largest
        hotel in Springfield
5. The royal arms hotel is the only hotel
        in Springfield.

GWD-24-Q 18:

    

Most household
appliances use electricity only when in use. Many microwave ovens,

    

However, have
built-in clocks and so use some electricity even when they are not in

    

Use. The clocks
each consume about 45 kilowatt-hours per year. Therefore, house

    

Holds whose
microwave oven has no built-in clock use 45 kilowatt-hours per year

    

Less. On average,
than do comparable households shoes microwave oven is other-

    

Wise similar but
has a built-in clock.

    

 

    

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

    

A.     Households that do not have a microwave
oven use less energy per year, on

    

average, than do households that have a microwave
oven.

    

B.     Microwave ovens with a built-in clock do
not generally cost more to buy than

    

microwave ovens without a built-in clock.

    

C.     All households that have a microwave oven
also have either a gas oven or a

    

Conventional electric oven.

    

D.     Households whose microwave oven does not
have a built-in clock are no more

    

likely to have a separate electric clock plugged in
than households whose

    

microwave oven has one.

    

E.      There are more households that have a
microwave oven with a built-in clock

    

than there are households that have a microwave oven
without a built-in clock.

GWD-24-40.

    

Scientists
typically do their most creative work before the age of forty. It is commonly
thought that this happens because aging by itself brings about a loss of
creative capacity. However, studies show that a disproportionately large
number of the scientists who produce highly creative work beyond the age of
forty entered their field at an older age than is usual. Since by the age
of forty the large majority of scientists have been working in their field for
at least fifteen years, the studies’ finding strongly suggests that the real
reason why scientists over forty rarely produce highly creative work is not
that they have simply aged but rather that they generally have spent too long
in a given field.

    

In the argument
given, the two portions in boldface play which of the following roles?

    

A.     The first is the position that the argument
as a whole opposes; the second is an objection that has been raised against a
position defended in the argument.

    

B.     the first is a claim that has been advanced
in support of a position that the argument opposes; the second is a finding
that has been used in support of that position.

    

C.     The first is an explanation that the
argument challenges; the second is a finding that has been used in support of
that explanation.

    

D.     The first is an explanation that the
argument challenges; the second is a finding on which that challenge is based.

    

E.      The first is an explanation that the
argument defends; the second is a finding that has been used to challenge that
explanation.
