When fish or mammals ingest the chemical rotenone, enzymes In (he digestive tract metabolize most of it, rendering It harmless, but If enough rotenone enters the bloodstream, It can kill them. Wildlife managers who use rotenone in rivers or lakes to reduce fish populations claim that the practice is harmless to aquatic mammals, but clearly if enough rotenone is used to kill fish, mammals must be at risk too.
Which of the following, if true, most seriously weakens the argument?
Which of the following statements concerning the valence model and the approach-withdrawal model most accurately reflects information provided in the Passage?
Buoyed by stability and economic growth at home, Russia has developed a foreign policy that seeks to reestablish its place as a key actor on the world stage.
For each of the four types of rooms in a certain hotel in June of last year, the table shows the number of rooms of that type in the hotel and the total number of nights booked, such that each night on which any given room is booked counts as one night booked. For example, because there were 10 rooms of the Garden Family type and there were 30 nights in June, the greatest possible number of nights booked for rooms of the Garden Family type was 10 multiplied by 30, or 300 (of which a total of 164 nights were actually booked). A room was considered vacant on any night on which it was not booked.
For each of the following room types in June of last year, select Yes if the average (arithmetic mean) number of vacancies (instances of a particular room being vacant on a particular night) per night for rooms of that type was greater than 2. Otherwise, select No.
If k is a positive integer and 5 k is a factor of the product of the odd integers from 99 to 199, inclusive, what is the greatest possible value of k?
The color red has been shown to induce greater aggression in people than the
color blue. Researchers conducted a study to determine whether such colorinduced aggression could influence the amount that consumers were willing to
pay for an identical product in online auction and online negotiation scenarios.
The researchers photographed a single item against each of four background
colors: blue, gray, white, and red. Using a computer, each participant in the study
viewed the item against exactly one of the four background colors. Half of the
participants were told the item was up for auction and were asked to submit their
highest bid for the item. The other half of the participants were told to negotiate
a price with the seller and were asked to offer the highest amount that they
would be willing to pay for the item.
The researchers expected that participants who viewed the red background
would typically behave more aggressively than those who viewed the blue
background. Among the auction group, the researchers hypothesized that more
aggressive participants would submit higher bids as they tried to beat other
potential bidders. Among the negotiation group, the researchers hypothesized
that more aggressive participants would make lower offers as they tried to
compete against the seller to get the best deal.
Assuming the researchers’ hypothesized link between offers and aggression is
correct, for each of the following background colors select More aggressive if, on
average, participants in the negotiation group in the study behaved more
aggressively when the product was displayed with that background color than the
participants did when the product was displayed with a gray background.
Otherwise, select Not more aggressive.
The Red Balloon Challenge was an experiment aimed at determining how quickly widely disbursed information could be gathered using social media. Competitors tried to locate 10 red weather balloons that had been tethered above random locations around the world in return for a $40,000 prize. The winning team located all of the balloons in just 9 hours, using an incentive-based strategy to encourage information sharing; The first person to send the correct coordinates of a particular balloon to the team received $2,000, but whoever recruited that person received $1,000, and the recruiter's recruiter received S500, and that person's recruiter received $250.
Select for 3 payments per balloon the amount of the prize money that the winning team would have remaining if they had to pay 3 people for each balloon located, and select for 4 payments per balloon the amount of the prize money that the winning team would have remaining if they had to pay 4 people for each balloon located. Make only two selections, one in each column.
Researchers studying long-term changes In regional mouse populations have found that by focusing on the populations of a rare but widespread and easily identifiable species of mouse (Species X), they can make fairly accurate estimations about the total regional mouse populations.
In a report on a recent study that Included the data tables that follow, the researchers provided some addenda:
1. "The Species X population of Region CV increased by 123,995 between 1990 and 2005.
2. In contrast, the Species X population of Region EW declined by about 52% during that same time.
The answer to which one of the following can be determined by using the information in the passage and tables?
