your first task was to find 125% of something. That would be easiest if your original number was a multiple of four.

We only know that counties with a high incidence of TV sets have a lower incidence of disease. We have no information as to whether the incidence will drop further. It may have reached the minimum afforded by TV watching. So C is not correct.

The stimulus tells us radio alone is enough to get the highest possible name recognition. It does not tell us anything about votes. There will always be candidates with high name recognition who do not get the most votes. Name recognition simply means awareness, not liking or approval.

The opposite of occasionally is "not occasionally". That does not mean sometimes. It means that they are not going to act on that motive.

E is incorrect because it changes the meaning. The original tells us that the economy caused the poor sales figures. E tells us that the government took action as a result of the poor sales figures. A amd B are tricky, but I prefer putting "as a result" closer to "sales figures" than to "depressed".

The stimulus tells us that the researchers are concluding that when a county has more TV sets, the residents stay indoors more often. This is only true of those residents actually stay inside to watch. A doesn't help us because we have no information about what counties are receiving programs to kil...

The initial statement is very simple. It gives you one fact: radio advertising will do the job. Any answer that brings in other factors such as votes or demographics will be out of scope.

Three issues here. 1. Who or what is imitating Louis Armstrong? Billie Holiday, not her technique. She uses her technique to imitate Armstrong. That eliminates A and B. 2. "Like" is followed by a noun phrase. C violates this rule. 3. In E, "musicians" should be possessive "musicians'". Also, the phr...

Try backsolving this one.
The dosage grew from 15 to 43 units, therefore the incremental dose on the last day was 28 units.
This means the total number of days in the study minus one (allowing the start day) has to be a factor of 28. Looking at our answer choices, only B works.
