The sound an elephant most commonly makes is a rumble that has a frequency that is too low to be heard by human ears. Elephants, meanwhile, can pick up these rumbles from over a mile away. Elephants live in “fission-fusion society,” splitting up and coming together while looking for food. Poring over recordings of female elephant calls, scientist Joyce Poole identified over a hundred different kinds of rumbles. When addressed with a rumble from a particular herdmate, especially an immediate family member, individual elephants jerked up their head and spread their ears wide, suggesting that -------Which choice most logically completes the text?rumbles are not the only form of communication used by elephant herds.eliminateelephant rumbles are occasionally too low-frequency to be understood by other elephants. eliminatein addition to having different types of rumbles, elephants also have unique, recognizable voices. eliminaterumbles are used by elephants to communicate a wide variety of information, including about the locations of food and predators.

Scientists have performed tests on social animals (like bees, monkeys, and humans) whose survival depends on cooperation to complete tasks and found that newborns of these species appear to show an innate attraction to auditory stimulation comprised of many individuals' calls or voices. A group of animal behaviorists recently performed a similar test on newborn Hawaiian monk seals. Unlike the species who were previously tested, monk seals are a notoriously solitary species that doesn't depend on cooperation for survival. When the scientists played audio of groups of seals barking, they found that infant seals showed a significant preference for the sounds, suggesting that -------Which choice most logically completes the text?group barking stimuli are likely perceived as harmless by newborns of social species that practice cooperation but as threatening by newborns of solitary species without cooperation.eliminateresearchers should not assume that an innate attraction to group barking stimuli in newborns is necessarily an adaptation related to social interaction or cooperation.eliminateresearchers can assume that attraction to group barking stimuli that is seen in social species that practice cooperation is learned rather than innate.eliminatenewborn Hawaiian monk seals show a stronger preference for group barking stimuli than adult Hawaiian monk seals do.

It was six men of IndostanTo learning much inclined,Who went to see the ElephantThough all of them were blind,[5]That each by observationMight satisfy his mind.The First approached the ElephantAnd, happening to fallAgainst his broad and sturdy side,[10]At once began to bawl:"God bless me, but the ElephantIs very like a wall!"The Second, feeling the tusk,Cried, "Ho! what have we here[15]So very round and smooth and sharp?To me 'tis very clearThis wonder of an ElephantIs very like a spear!"The Third approached the animal[20]And, happening to takeThe squirming trunk within his hands,Thus boldly up he spake:"I see," quoth he, "The ElephantIs very like a snake!"[25]The Fourth reached out an eager hand,And felt about the knee:"What most the wondrous beast is likeIs very plain," quoth he;"Tis clear enough the Elephant[30]Is very like a tree!"The Fifth, who chanced to touch the ear,Said, "Even the blindest manCan tell what this resembles most;Deny the fact who can:[35]This marvel of an elephantIs very like a fan!"The Sixth no sooner had begunAbout the beast to gropeThen, seizing on the swinging tail[40]That fell within his scope,"I see," quoth he, "the ElephantIs very like a rope!"And so these men of IndostanDisputed loud and long,[45]Each in his own opinionExceeding stiff and strong.Though each was partly in the right,They all were in the wrong!The Blind Men and the Elephant by John Godfrey Saxe is in the public domain.Unless otherwise noted, this content is licensed under theCC BY-NC-SA 4.0 licenseRead AloudAnnotateTranslateAssessment QuestionsShow Less12345As a parable, or a simple story used to illustrate a lesson, what knowledge or moral does the poem impart to the audience?
