Complement of Set A

Definition: The complement of a set A, denoted as A', consists of all elements that are not in set A but are in the universal set.
In this case: If the complement of set A has 0 elements, it means that there are no elements in the universal set that are not in set A.
Explanation: If the complement of set A has 0 elements, it implies that set A itself contains all elements in the universal set. Therefore, there are no additional elements outside of set A to form its complement.
Conclusion: The correct answer is option 'A', which states that there are 0 elements in the complement of set A.

The cartoon series enjoyed by young and oldalike revolved mostly around the misadventures of this(5) loveable bear and his sidekick Boo-Boo as theyattempted to snag “pic-a-nic” baskets in the made-upland of Jellystone Park. It’s not often that people thinkabout where the ideas for these cartoons characterscome from, which brings up an interesting point: do(10) bears actually search for food left in picnic basketsand unattended campsites? Anyone who has watchedan episode of Yogi Bear can see that the bears’ behav-ior goes far beyond the limits of what is natural. Thething which must be explored, then, is which of those(15)humorous antics were license on the part of Hanna-Barbera, and which were actually based on the bear’snormal behaviors.Remarkably enough, bears have been known toseek out food from some unlikely sources, including(20)picnic baskets, on top of their usual diet of berries,insects, and fish. Bears work throughout the summerand fall to build up fat stores so as to have energyenough to last them through their winter hibernations.Related to this is their need to replenish their depleted(25)reserves when they wake up in the spring. Food is gen-erally scarce in the early spring, and consequently theywill gladly indulge in any foods that are high in pro-teins or fats. This is the main reason for many incidentsinvolving bears entering campsites in search of food.(30)Although this behavior may seem strange, it isno more than the result of nature equipping bears witha variety of traits that allow them to remain well fedin increasingly human-populated habitats. Specifically,the American black bear, Ursus americanus, has color(35)vision and has been observed by scientists using itscolor vision to distinguish between varying food itemsat close range. On top of this, all bears have an acutesense of smell and can use their especially sensitive lipsto locate food. These sensory talents contribute to the(40)bears’ remarkably high intelligence and curiosity, giv-ing them the ability to open closed containers if theybelieve food is inside. Their exploratory and naviga-tional skills are also worthy of note—most bears willmaintain vast territories in order to obtain food from(45)a variety of sources. Bears may even vary their sleepcycles in areas where there is a large degree of humanactivity, either feasting on road-side garbage during theday or scouring campsites for leftovers at night.Yet another strange but true comparison is that(50)Yogi and Boo-Boo have developed a social relationshipmuch like the ones that will form between wild bearswhen several animals find themselves sharing a limitednumber of food sources. Generally solitary, black bearswill create a hierarchical order in situations where paths(55)cross in pursuit of food, so as to assure that all animalsremain adequately fed. While it is unlikely that anyblack bears in nature would actually send a cub after acamper’s lunch, the behavioral relationships that mightinspire the creation of such a story are indeed real.(60)Though many of the features of the comical YogiBear are likely the result of pure imagination, thereis scientific fact behind at least some of his activities.Despite his apperance as a brown bear, the distinctivefeeding behaviors of the American black bear match(65)remarkably well with the habits of the cartoonish cul-prit. The uncanny truth behind little known scientificfacts such as these should make everyone think twicethe next time they sit down to watch Saturday morningcartoons.Q.As it is used in line 37, the word acute most nearly means

Passage adapted from “Utopia” by Thomas More (1516) inIdeal Commonwealths:Comprising Mores Utopia, Bacons New Atlantis, Campanellas City of the Sun, and Harringtons Oceans(1901)Thus have I described to you, as particularly as I could, the constitution of that commonwealth, which I do not only think the best in the world, but indeed the only commonwealth that truly deserves that name.In all other places it is visible that, while people talk of a commonwealth, every man only seeks his own wealth; but there, where no man has any property, all men zealously pursue the good of the public, and, indeed, it is no wonder to see men act so differently, for in other commonwealths every man knows that unless he provides for himself, how flourishing soever the commonwealth may be, he must die of hunger, so that he sees the necessity of preferring his own concerns to the public; but in Utopia, where every man has a right to everything, they all know that ifcare is taken to keep the public stores fullno private man can want anything, for among them there is no unequal distribution, so that no man is poor, none in necessity, and though no man has anything, yet they are all rich; for what can make a man so rich as to lead a serene and cheerful life, free from anxieties, neither apprehending want himself, nor vexed with the endless complaints of his wife?He is not afraid of the misery of his children, nor is he contriving how to raise a portion for his daughters, but is secure in this, that both he and his wife, his children and grandchildren, to as many generations as he can fancy, will all live both plentifully and happily, since, among them, there is no less care taken of those who were once engaged in labor, but grow afterwards unable to follow it, than there is, elsewhere, of these that continue still employed.I would gladly hear any man compare the justice that is among them with that of all other nations;among whommay I perish if I see anything that looks either like justice or equity; for what justice is there in this: that a nobleman, a goldsmith, a banker, or any other man, who either does nothing at all, or, at best, is employed in things that are of no use to the public, should live in great luxury and splendor upon what is so ill acquired, and a mean man, a carter, a smith, or a plowman, who works harder even than the beasts themselves, and is employed in labors so necessary, that no commonwealth could hold out a year without them, can only earn so poor a livelihood and must lead so miserable a life, that the condition of the beasts is much better than theirs? For as the beasts do not work so constantly, so they feed almost as well, and with more pleasure, and have no anxiety about what is to come, whilst these men are depressed by a barren and fruitless employment, and tormented with the apprehensions of want in their old age; since that which they get by their daily labour does but maintain them at present, and is consumed as fast as it comes in, there is no overplus left to lay up for old age.Q.
