Which of the following most logically completes the argument?
A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb's high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.

Which of the following most logically completes the passage?
Most bicycle helmets provide good protection for the top and back of the head, but little or no protection for the temple regions on the sides of the head. A study of head injuries resulting from bicycle accidents showed that a large proportion were caused by blows to the temple area. Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced especially since _________.

A certain mayor has proposed a fee of five dollars per day on private vehicles entering the city, claiming that the fee will alleviate the city's traffic congestion. The mayor reasons that, since the fee will exceed the cost of round-trip bus fare from many nearby points, many people will switch from using their cars to using the bus.
Which of the following statements, if true, provides the best evidence that the mayor's reasoning is flawed?

During the month of May, crabs arrive on Delaware's beaches to lay eggs. Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds. Delaware's crab population has declined recently. This decline, however, poses no serious threat to the migrating shorebird populations: by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
Which of the following, if true, most seriously weakens the argument?

Editorial: Regulations recently imposed by the government of Risemia call for unprecedented reductions in the amounts of pollutants manufacturers are allowed to discharge into the environment. It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations. Resultant price increases for Risemian manufactured goods will lead to the loss of some export markets. Clearly, therefore, annual exports of Risemian manufactured goods will in the future occur at diminished levels.
Which of the following, if true, most seriously weakens the argument in the editorial?

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.
Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

The average size of marine life that washes up on the shore of the Japanese island Ryukyu is smaller than the average size that washes up on the Western coast of Australia. Giant squid have recently been found washed up on the shores of Ryukyu as well as the Western coast of Australia. It can be concluded that the average size of the giant squids on the shore Ryukyu must be less than that of giant squids washed up on the shores of Western Australia.
The argument above can be attacked on the grounds that it does which of the following?

The price of the SuperPixel high definition television, by Lux Electronics, has typically been out of the range of most consumers, a few of whom nonetheless save up for the television. This past July, the SuperPixel reduced its price by 40%, and sales during that month nearly tripled. TechWare, a popular electronics magazine, claims that the SuperPixel television should continue to see sales grow at this rate till the end of August. Which of the following suggests that TechWare's forecast is misguided?

Bankruptcy is a process that depends on a variety of structural, fiscal, and human variables. These variables are different at every company. Therefore, the pattern of companies declaring bankruptcy should be random. Yet tax records from 2010 demonstrate a pattern: a large number of companies throughout the United States declared bankruptcy at the same time.Which of the following, if true, forms the best basis for at least a partial explanation for the pattern of bankruptcy shown by the tax records?

Federal investigators, called in at the request of the management of Ploutos National Bank, recently apprehended a ring of seven embezzlers from among the bank's employees. The bank management decided to call in the federal investigators when they were unable to account for millions of dollars missing in their budget for this year. All the funds those seven individuals embezzled have been returned to the bank, and that accounts for about two thirds of the total amount missing. All seven of the accused have plea-bargained to avoid trial and are now serving in prison on reduced sentences.Which of following conclusions can most properly be drawn from the information above?

Two years ago, the human resources department at Harrison's Technologies had 175 sexual harassment cases open, a number that at that time led all companies in the sector. At that time, a typical claim took six months to process and clear. In response to this high number, the CEO's Advisory Team published a comprehensive set of guidelines for training employees in the identification and avoidance of behaviors that could constitute sexual harassment. At this writing, the human resources department has only sixty sexual harassment cases open. Clearly, the guidelines published by the CEO's Advisory Team were effective in reducing the occurrence of new sexual harassment claims at Harrison's Technologies. Which of the following, if true, most seriously weakens the conclusion above?

The Bluetail Moonbeam, endemic to the streams and rivers of Asia, is regularly imported into the United States by companies wishing to breed it for food. An infectious virus has been threatening Bluetail Moonbeam stocks in the United States. Even before a Bluetail Moonbeam develops any symptoms, biologists can establish the presence of the infection by an inexpensive test for antibodies in the fish's blood. Yet, after the instance of infection, antibodies take about four weeks to appear in the fish's blood, and the test will find no results before then. Catching a live Bluetail Moonbeam and shipping it to the United States takes a little more than a week. Once the Bluetail Moonbeam is in captivity, shippers can eliminate all new sources of infection, but unfortunately, some Bluetail Moonbeams might be infected days or even hours before being caught. Thus, even running the antibody test on each Bluetail Moonbeam entering the country would still allow infected fish into the American stocks.Which of the following, if performed by the government, could logically be expected to overcome the problem with the plan to limit the spread of this virus in the Bluetail Moonbeam?

The blue-tipped puffer is a migratory bird that is found along the coast of this state in summer months. The puffers enjoy the seeds of Thomson's Mulberry trees; because these trees are plentiful in the state's Coastal Park, traditionally many blue-tipped puffers would be found in the park during summer months. Ten years ago, the grey fox, a primary predator of the puffer, was re-introduced into the park, and its numbers have been thriving. Over that time, we have seen many fewer puffers in the park during the summer months. Clearly, the puffers are choosing to spend their summers elsewhere. Which of the following would be the most important to determine in order to evaluate the argument?

Linguist: Each language has a word that captures a concept or emotional state in a way that no other language does. To capture such a breadth of expression, an artificial language should be created that contains words corresponding to all the different concepts and emotional states captured by the world's languages. That is not to say that such a language would contain as many words as there are in all the world's languages. Rather, only for those words that have no corresponding word in another language. While such a plan is hugely ambitious, the resulting language would be more thorough than any existing language.

The Malbec grape, originally grown in France, has become the main varietal in Argentina. This is surprising because most Malbec grown in Argentina is grown at high altitudes, whereas the Malbec grape once was grown at low altitudes. Therefore, Argentinian winegrowers should grow the Malbec grape at low elevations.Which of the following, if true, would most weaken the conclusion of the argument?
