Designer: Any garden and adjoining living room that are separated from one another by sliding glass doors can visually merge into a single space. If the sliding doors are open, as may happen in summer, this effect will be created if it does not already exist and intensified if it does. The effect remains quite strong during colder months if the garden is well coordinated with the room and contributes strong visual interest of its own.
Summary
A Designer says that any garden and adjoining living room separated by a sliding glass door can visually merge into a single space. If the doors are left open, this effect will be created if it is not already present. If they are already visually merged, the effect will be intensified. If the garden is well coordinated with the room and contributes a strong visual interest, the effect will remain quite strong during colder months.
Strongly Supported Conclusions
If the sliding doors are closed, this effect can/cannot be present.
If the doors are left open, this effect will be present.
A
A garden separated from an adjoining living room by closed sliding glass doors cannot be well coordinated with the room unless the garden contributes strong visual interest.
The stimulus does not give this condition. The stimulus only says that being well coordinated and contributing a strong visual interest is sufficient for the effect to remain strong in the winter.
B
In cold weather, a garden and an adjoining living room separated from one another by sliding glass doors will not visually merge into a single space unless the garden is well coordinated with the room.
This is too strong to support. The stimulus says that the effect will remain *strong* if the room is well coordinated and contributes a strong visual interest. The stimulus gives no condition that can conclude that the room does not visually merge.
C
A garden and an adjoining living room separated by sliding glass doors cannot visually merge in summer unless the doors are open.
This is antisupported. The doors being open in the summer *enhances* the effect if it is already present and provides the effect if it is not.
D
A garden can visually merge with an adjoining living room into a single space even if the garden does not contribute strong visual interest of its own.
This reflects the reasoning in the stimulus. The room contributing a strong visual interest is only linked to the effect remaining quite strong during *colder* months. The room can still visually merge without this condition.
E
Except in summer, opening the sliding glass doors that separate a garden from an adjoining living room does not intensify the effect of the garden and room visually merging into a single space.
This is antisupported. The stimulus only uses summer as an example, not a definitive rule. The stimulus says that the effect will be enhanced or created if the doors are left open and does not specify any time of year.
Last summer, after a number of people got sick from eating locally caught anchovies, the coastal city of San Martin advised against eating such anchovies. The anchovies were apparently tainted with domoic acid, a harmful neurotoxin. However, a dramatic drop in the population of P. australis plankton to numbers more normal for local coastal waters indicates that it is once again safe to eat locally caught anchovies.
"Surprising" Phenomenon
Why does the decrease in plankton numbers make the anchovies safe to eat?
Objective
The correct answer will establish a relationship between the number of P. australis and the safety of the anchovies. It will imply that fewer plankton means less domoic acid in the anchovies or that a decrease in plankton makes the domoic acid in anchovies safer to consume.
A
P. australis is one of several varieties of plankton common to the region that, when ingested by anchovies, cause the latter to secrete small amounts of domoic acid.
This states that anchovies will secrete, not contain, domoic acid after ingesting P. australis. It is not implied that anchovies secreting domoic acid must contain that acid, nor that domoic acid in the water builds up in anchovies’ bodies.
B
P. australis naturally produces domoic acid, though anchovies consume enough to become toxic only when the population of P. australis is extraordinarily large.
This explains why a decrease in P. australis numbers makes the anchovies safe. Once the plankton are less prevalent, the domoic acid in anchovies lowers to safe levels.
C
Scientists have used P. australis plankton to obtain domoic acid in the laboratory.
This does not imply that high P. australis numbers cause anchovies to contain domoic acid. It is possible that P. australis does not naturally produce or contain domoic acid, in which case its relationship to the anchovies remains unexplained.
D
A sharp decline in the population of P. australis is typically mirrored by a corresponding drop in the local anchovy population.
This does not explain why locally caught anchovies are safe to eat. It does not imply that the surviving anchovies are in any way safer to consume.
E
P. australis cannot survive in large numbers in seawater that does not contain significant quantities of domoic acid along with numerous other compounds.
This establishes a condition necessary for the survival of P. australis, but does not imply that a decrease in plankton must accompany a decrease in domoic acid. It is possible the plankton died for a different reason and domoic acid is still prevalent in the water.
Brigita: That traditional definition of full employment was developed before the rise of temporary and part-time work and the fall in benefit levels. When people are juggling several part-time jobs with no benefits, or working in a series of temporary assignments, as is now the case, 5 percent unemployment is not full employment.
A
what definition of full employment is applicable under contemporary economic conditions
B
whether it is a good idea, all things considered, to allow the unemployment level to drop below 5 percent
C
whether a person with a part-time job should count as fully employed
D
whether the number of part-time and temporary workers has increased since the traditional definition of full employment was developed
E
whether unemployment levels above 5 percent can cause inflation levels to rise
