Answer: D - The value of the expression is 29/21.(54-24)/(54-2×〖10〗2 + 24 ) = ((52 )2-(22 )2)/((52 )2-2×52×22 + (22 )2 ) = ((52-22 )(52 + 22))/(52-22 )2 = (52 + 22)/(52-22 ) = 29/21

Explanation

Answer: D - The value of the expression is 29/21.
(5⁴-2⁴)/(5⁴-2×〖10〗² + 2⁴ ) = ((5² )²-(2² )²)/((5² )²-2×5²×2² + (2² )² ) = ((5²-2² )(5² + 2²))/(5²-2² )² = (5² + 2²)/(5²-2² ) = 29/21

Should Medicare be Changed?Dating back to the 1960s, Medicare, a social insurance program, has presented America’s elderly and disabled populations with health benefits for nearly six decades. As expressed in “Understanding Social Insurance: Fairness, Affordability, and the ‘Modernization’ of Social Security and Medicare”, much debate surrounds the basic controversy of whether the structure of Medicare requires change. Undoubtedly, Medicare needs to be left to function in order to offer benefits and hope to those across the United States. For many the idea of transforming Medicare from its core component of availability for all without individual risk is ideal. These economists view changes within Medicare as a way to reward the individual with personal choice and increased marketization (Marmor and Mashaw 2006). But what they are deceitfully hiding is that such changes would shake the core of Medicare, shattering its fundamental basis and leaving vast populations of people to sort through healthcare decisions that they have not been adequately informed to make, thus creating inadequate social insurance protection (Marmor and Mashaw 2006). Social insurance, which includes Medicare in its current state, is desirable because it gives a concept of protection and equality to the elderly and disabled populations throughout the United States. Given that this is a key feature of all advanced industrial societies (Marmor and Mashaw 2006), it seems that altering such social insurance programs would make Americans devoid of a protection that has assisted America’s industrial capitalism (Marmor and Mashaw 2006). Ironically, it seems that those who want to change what has worked for decades are failing to fully consider the ramifications of changing one of the key structures in a capitalistic society; they are willing instead to adopt new approaches that tend to take care of the rich and neglect the rest. Medicare has been successful for decades; therefore, what is working should not be changed.What does the word devoid mean as it is used in the third paragraph?

After a peak period of exploration and classification of new species in the 1930s, the discovery of new creatures on the planet dropped significantly and has continued to decline. It is tempting, in light of the decreasing frequency of new identifications, to believe that all of the species in the natural world have been discovered. That, however, is not the case. In fact, in August of 2013, researchers from the Smithsonian’s National Museum of Natural History confirmed the discovery of a new species of mammal, the olinguito. The first indication that a new species might exist was identified in 2003. Kristofer Helgen, the curator of mammals at the museum, was evaluating specimens at a museum in Chicago when he discovered a collection of pelts that he had never seen before. “They were these rich, red skins with flowing fur,” noted Helgen. The data gathered with the skins identified their native locale as the northern Andes Mountains, at elevations higher than those common to the olingo, a related species they somewhat resembled. Spurred on by this discovery, Helgen assembled a team of researchers from the United States and Ecuador and set out to search for the animal in the Otanga Cloud Forest Preserve of Ecuador. The team happened upon the animal their first night in the jungle. Through their work on that first journey and several subsequent trips the team not only confirmed the existence of the new species, but also four subspecies. In their research, the team discovered that a live olinguito actually lived in the United States during the 1960s. The female olinquito was moved from zoo to zoo and refused to mate with olingos. Although the olinguito was only identified recently, it is neither rare nor endangered. Researchers estimate that thousands of the animals inhabit the forests of the preserve. The only major threat is the impact of deforestation on their habit, and even that, to this point, doesn’t seem to have a serious effect. The time between Helgen’s discovery of the pelts and the announcement of a new species indicates:
