Quant Command of Evidence Quiz

Which choice best uses information from the graph to complete the statement?Passage:To test whether having more choices results in slower decision making, a student conducted an experiment with four of her classmates as participants. She presented them with different flavors of ice cream in sets of five, four, three, and two; for each set, she recorded how long it took each student to name a favorite flavor from among those in the set. The student had predicted that decision making time would progressively decrease as the number of flavors decreased. This prediction is most aligned with the results from _______

A student 1 and student 3. B student 2 and student 3. C student 2 and student 4. D student 3 and student 4.

Which finding, if true, would most directly support the researchers’ comparison of different urban areas?Passage:In urban environments, noise pollution levels can fluctuate widely, influenced by traffic volume and urban planning. To assess these variations, Thomas E. Beck and his team used mobile sensor networks to capture the dominant decibel levels across different city zones. The researchers categorized decibel levels of 70 dB and below as moderate, decibel levels between 70 and 90 dB as loud, and decibel levels of 90 dB and above as very loud. Their comparison of urban areas revealed that commercial districts exhibit higher noise levels than residential areas due to heavier traffic and business activities.

A The commercial zones consistently registered noise levels above 90 dB, categorizing them as very loud according to the established decibel level classifications. B In residential areas, the dominant decibel levels were frequently recorded at 70 dB or below, indicating moderate noise pollution. C In zones transitioning from residential to commercial, there was a marked increase in decibel levels from below 70 dB to above 90 dB. D Across various urban zones, the average decibel levels were found to be well above 70 dB, highlighting general loudness throughout the city.

Which finding from Fernandez and his colleagues’ study, if true, would most directly challenge the assumption in the underlined sentence?Passage:While most mammals have fur or hair covering their bodies, some species have developed specialized adaptations such as thick layers of blubber to protect them from extreme cold temperatures. Many biologists have assumed that these specialized adaptations would enable mammals to inhabit a wider range of environments, including polar regions. To assess this assumption, a team of researchers led by marine biologist Dr. Alejandro Fernandez analyzed data for over 1,000 species of mammals.

A Higher metabolic rates are observed in species with specialized adaptations compared to those without such adaptations. B Species with specialized adaptations typically exhibit smaller body sizes compared to those without such adaptations. C Species with specialized adaptations often depend more on local food sources available in their habitats than those without such adaptations. D Species with specialized adaptations tend to have more restricted distribution ranges than those without such adaptations.
