One important rule in data gathering is, the more data we can gather on a population, the more reliable our statistics about that population will be. More specifically, the greater fraction of the population we can sample, the smaller our margin of error from the true value of the population statistic. Another important rule in data gathering is the more similar our sample is to the population of interest, the smaller our statistical error will be. Since the sample size is highest and the group is most like the population (of undergraduate computer science majors) in choice (A), that group should produce the smallest margin of error in the data.

Question based on the following passage.This passage is adapted from Patricia Waldron, “Why Birds Fly in a V Formation.” ©2014 by American Association for the Advancement of Science.Anyone watching the autumn sky knows thatmigrating birds fly in a V formation, but scientistshave long debated why. A new study of ibises findsthat these big-winged birds carefully position their(5) wingtips and sync their flapping, presumably to catchthe preceding bird’s updraft—and save energyduring flight.There are two reasons birds might fly in aV formation: It may make flight easier, or they’re(10) simply following the leader. Squadrons of planes cansave fuel by flying in a V formation, and manyscientists suspect that migrating birds do the same.Models that treated flapping birds like fixed-wingairplanes estimate that they save energy by drafting(15) off each other, but currents created by airplanes arefar more stable than the oscillating eddies coming offof a bird. “Air gets pretty unpredictable behind aflapping wing,” says James Usherwood, a locomotorbiomechanist at the Royal Veterinary College at the(20) University of London in Hatfield, where the researchtook place.The study, published in Nature, took advantage ofan existing project to reintroduce endangerednorthern bald ibises (Geronticus eremit

A researcher conducted an experiment inspired by studies suggesting that people may benefit from feeling frightened in certain circumstances, such as when watching scary movies or visiting haunted attractions. The researcher recruited several participants and had them walk through a local haunted house attraction. Immediately after exiting the attraction, each participant completed a survey about their experience. Based on the survey responses, the researcher claims that feeling frightened in controlled situations can boost a persons mood and confidence.Which quotation from a participant would best illustrate the researchers claim?

Text 1What factors influence the abundance of species in a given ecological community? Some theorists have argued that historical diversity is a major driver of how diverse an ecological community eventually becomes: differences in community diversity across otherwise similar habitats, in this view, are strongly affected by the number of species living in those habitats at earlier times.Text 2In 2010, a group of researchers including biologist Carla Cáceres created artificial pools in a New York forest. They stocked some pools with a diverse mix of zooplankton species and others with a single zooplankton species and allowed the pool communities to develop naturally thereafter. Over the course of four years, Cáceres and colleagues periodically measured the species diversity of the pools, finding—contrary to their expectations—that by the end of the study there was little to no difference in the pools species diversity.Based on the texts, how would Cáceres and colleagues (Text 2) most likely describe the view of the theorists presented in Text 1?

While researching a topic, a student has taken the following notes:· As engineered structures, many bird nests are uniquely flexible yet cohesive.· A research team led by Yashraj Bhosale wanted to better understand the mechanics behind these structural properties.· Bhosales team used laboratory models that simulated the arrangement of flexible sticks into nest-like structures.· The researchers analyzed the points where sticks touched one another.· When pressure was applied to the model nests, the number of contact points between the sticks increased, making the structures stiffer.The student wants to present the primary aim of the research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Business researcher Melanie Brucks and colleagues found that remote video conference meetings may be less conducive to brainstorming than in-person meetings are. The researchers suspect that video meeting participants are focused on staring at the speaker on the screen and dont allow their eyes or mind to wander as much, which may ultimately ______ creativity.Which choice completes the text with the most logical and precise word or phrase?
