A study found that people who regularly consume certain nuts have a lower risk of cardiovascular disease. Researchers hypothesized that this might be due to the protective effects of unsaturated fatty acids found in these nuts. However, subsequent studies showed that consuming other foods containing unsaturated fatty acids did not reduce the risk of cardiovascular disease. Therefore, the researchers concluded that the cardioprotective effects of certain nuts may be attributed to components other than unsaturated fatty acids.
Which of the following, if true, would most weaken the researchers' conclusion?
(A) The types and quantities of unsaturated fatty acids vary among different nut species.
(B) The cardioprotective effects of unsaturated fatty acids are only manifest when combined with other nutrients uniquely found in certain nuts.
(C) Consuming certain nuts may also reduce the risk of developing certain types of cancer and neurodegenerative diseases.
(D) Culinary processing can destroy some of the nutritional components in nuts, thus diminishing their cardioprotective effects.
(E) Excessive consumption of any type of nut may lead to weight gain, thereby increasing the risk of cardiovascular disease.
Due to the construction of four dams, the population of a certain species of fish has drastically declined. The fish are supposed to swim upstream to spawn, but the dams block their path. A plan has been proposed to remove the dams with the goal of restoring the fish population to its original level. Which of the following, if true, would most strongly support the plan to remove the dams?
A. There are currently no alternative breeding sites for the fish downstream of the dams.
B. The largest of the dams is located on the river with the highest concentration of this species of fish.
C. Removing smaller dams in the past has led to a significant increase in the fish population.
D. The species of fish is known to migrate significant distances to reach suitable spawning grounds.
E. Technological advancements have made the removal of the dams more feasible and less disruptive to the local community.

Over the past decade two subfields of science, cosmology and elementary-particle physics, have become married in a symbiotic relationship that has produced a number of exciting offspring. These offspring are beginning to yield insights on the creation of spacetime and matter at epochs as early as 10^43to 10^35 second after the birth of the universe in the primordial explosion known as the big bang. Important clues to the nature of the big bang itself may even come from a theory currently under development, known as the ultimate theory of everything (T.O.E.). A T.O.E. would describe all the interactions among the fundamental particles in a single bold stroke.
The confluence of cosmology and particle physics is even changing the way science is done. Traditionally astronomy has been an observational rather than an experimental science, in which passive observations were made with telescopes and actively controlled experiments have been virtually unknown. Traditionally the tools of particle physics have been high-energy accelerators. Now that cosmology has begun to make predictions about elementary-particle physics, it has become conceivable that those cosmological predictions could be checked with carefully controlled accelerator experiments. It has taken more than 10 years for accelerators to reach the point where they can do the appropriate experiments, but the experiments are now in fact in progress. The preliminary results confirm the predictions from cosmology.
It appears therefore that cosmology has become a true science in the sense that ideas not only are developed but also are being tested in the laboratory on time scales that are shorter than a scientist’s lifetime. This is a far cry from earlier as in which cosmological theories proliferated and there was little way to confirm or refute any of them other than on their aesthetic appeal. Conversely, telescopes may eventually be employed to test ideas from fundamental physics, such as proposals for a T.O.E. Indeed, tests of theories involving interactions of particles with enormous energies could very well have only one available laboratory: the big bang itself.
1. The passage suggests that the confluence of cosmology and particle physics has led to:
A) a paradigm shift in the way science is conducted, with cosmology becoming more experimental and particle physics more observational
B) a complete understanding of the fundamental interactions among particles and the origin of the universe
C) a realization that cosmology and particle physics are fundamentally incompatible fields of study
D) a rejection of the traditional tools and methods used in both cosmology and particle physics
E) a confirmation that the aesthetic appeal of a theory is the most important criterion for its acceptance
2. According to the passage, the concept of using telescopes to test ideas from fundamental physics is:
A) a well-established practice that has been used for decades
B) a novel idea that has yet to be implemented in practice
C) a futile endeavor, as the big bang is the only available laboratory for such tests
D) a contradiction to the principle that cosmology is an observational science
E) a natural consequence of the merger between cosmology and particle physics
3. The author's stance on the possibility of developing a Theory of Everything (T.O.E.) can be best described as:
A) highly skeptical, as the author believes it to be an unattainable goal
B) cautiously optimistic, as the author suggests that it is currently under development
C) neutral, as the author does not express a strong opinion on its feasibility
D) dismissive, as the author implies that it would be irrelevant to the study of the early universe
E) enthusiastic, as the author suggests that it would provide a complete understanding of all fundamental interactions
4. The passage implies that the time scale for confirming or refuting cosmological theories:
A) has been significantly reduced due to the confluence of cosmology and particle physics
B) remains much longer than a scientist's lifetime, making cosmology a purely theoretical field
C) is irrelevant, as cosmological theories are judged solely on their aesthetic appeal
D) has become longer due to the increased complexity of the theories being developed
E) is determined primarily by the availability of observational data from telescopes
5. The author's primary purpose in mentioning the preliminary results of accelerator experiments is to:
A) highlight the limitations of using particle accelerators to test cosmological predictions
B) demonstrate the superiority of observational methods over experimental methods
C) argue for increased funding for the construction of more powerful accelerators
D) provide evidence that supports the predictions made by cosmological theories
E) challenge the notion that cosmology and particle physics are related fields
6. The passage suggests that the ultimate laboratory for testing theories involving interactions of particles with enormous energies is:
A) high-energy accelerators, as they can recreate the conditions of the early universe
B) the big bang itself, as it involves energies far beyond those achievable in accelerators
C) telescopes, as they can directly observe the remnants of the early universe
D) computer simulations, as they can model the behavior of particles at extreme energies
E) none of the above, as such theories are untestable and purely speculative
7. The author's tone throughout the passage can be best described as:
A) cynical and pessimistic about the future of cosmology and particle physics
B) excited and hopeful about the potential insights to be gained from the confluence of cosmology and particle physics
C) neutral and objective, presenting the facts without any emotional engagement
D) critical and disapproving of the trend towards greater collaboration between cosmology and particle physics
E) nostalgic for the traditional approaches to cosmology and particle physics
8. The main idea of the passage is that:
A) cosmology and particle physics have become increasingly divergent fields with little common ground
B) the confluence of cosmology and particle physics has led to significant advances in our understanding of the early universe and the fundamental interactions among particles
C) the traditional tools and methods of cosmology and particle physics are no longer relevant in the modern era
D) the development of a Theory of Everything (T.O.E.) is the ultimate goal of both cosmology and particle physics
E) the big bang is the only valid laboratory for testing theories in cosmology and particle physics
