  • a)
    Living creatures on another planet would probably have the same appearance as those on Earth.
  • b)
    Life cannot exist on other planets in our solar system.
  • c)
    If the appropriate physical conditions exist, life is an inevitable consequence.  
  • d)
    More than one of the suns in the galaxy is accompanied by an Earth-like planet.
  • e)
    It is likely that life on another planet would require conditions similar to those on Earth.

In stating that planets may exist that are similar enough to Earth to make them suitable for supporting life, the author implicitly rules out planets dissimilar to Earth as likely to support life. The assumption underlying the statement is that life on another planet is likely to require conditions similar to those on Earth. Therefore, E is the correct answer. A is not correct. The statement presupposes nothing about the appearance of extraterrestrial life. B is incorrect. The statement implies that it is relatively unlikely that life exists on other planets in our solar system, but it makes no presupposition absolutely ruling out the possibility that such life exists. The answer choice of C is incorrect. Although the statement suggests that there is the greatest chance for life when physical conditions are appropriate, it leaves open the possibility that no life will exist even with appropriate conditions. D is also incorrect. The statement says that it is possible that more than one of the suns in the galaxy is accompanied by an Earth-like planet, but it does not presuppose that there are actually any such suns.

The presupposition in the given statement is:

The greatest chance for the existence of extraterrestrial life is on a planet beyond our solar system. The Milky Way galaxy alone contains 100 billion other suns, many of which could be accompanied by planets similar enough to Earth to make them suitable abodes of life.

Explanation:

The given statement implies that the greatest chance for finding extraterrestrial life is not within our solar system but on a planet beyond it. It further states that the Milky Way galaxy, which contains 100 billion suns, could have planets similar to Earth that could potentially support life. This statement presupposes the following:

Life on another planet would require conditions similar to those on Earth:
The statement suggests that planets similar enough to Earth could be suitable abodes of life. This implies that life on another planet would require conditions that are similar to or compatible with the conditions we find on Earth. It presupposes that the presence of certain physical conditions, such as the right temperature range, availability of water, and suitable atmosphere, are necessary for the existence of life.

Other planets in our solar system are not suitable for life:
The statement focuses on planets beyond our solar system as having the greatest chance for extraterrestrial life. This presupposes that the other planets in our solar system, such as Mars or Venus, are not suitable for hosting life. It suggests that the conditions on these planets are not compatible with the existence of life as we know it.

Multiple suns in the Milky Way galaxy could have Earth-like planets:
The statement mentions that the Milky Way galaxy contains 100 billion other suns, many of which could be accompanied by planets similar enough to Earth. This presupposes that there are multiple suns in the galaxy that have Earth-like planets orbiting them. It suggests that the diversity of suns in the galaxy increases the likelihood of finding planets with suitable conditions for life.

In conclusion, the statement presupposes that life on another planet would require conditions similar to those on Earth, that other planets in our solar system are not suitable for life, and that multiple suns in the Milky Way galaxy could have Earth-like planets. Therefore, the correct answer is option E.

Similar GMAT Doubts

For millennia, the Nile River flooded nearly every year as a natural consequence of heavy summer rains on the Ethiopian Plateau; in the last century, as the population in the region exploded, the cycle of flooding interspersed with periodic drought caused widespread suffering for the local population. In the mid-1950s, the Egyptian government concluded that a significant dam was necessary to enable the country’s economic development to be on a par with that of Western nations. The Aswan Dam would prevent the annual flooding, generate hydroelectric power and supply a steady source of water for residents and agricultural activities, though it would also have other, less positive effects.By the 1970s, most Egyptian villages had electric power, and the dam provided approximately half of Egypt’s entire output of electricity. The benefits were counteracted, however, by consequences which were sometimes slow to appear but ruinous in their long-term effects. Dams prevent silt from flowing through to downstream lands.The silt is essential for renewing the minerals and nutrients that make the land fertile; before the dam, the Nile floodplain was famously productive. Farmers have had to substitute artificial fertilizers, reducing profits and causing pervasive chemical pollution with deleterious effects for the human, animal and plant populations living near or in the river. It is difficult to draw definite conclusions about a project with such substantial and varied results, but it would be untenable to assert that the Egyptian government should never have built the Aswan Dam.Q.Based upon the content of the passage, the author would most likely agree with which of the following propositions?

Read the passage and answer the question given below.Scandals involving authors of memoirs have raised questions about how much artistic license should be allowed in a purported work of nonfiction. By definition, nonfiction works are about facts and real events, but perception of real events can vary greatly depending on the point of view of the writer, especially an author recounting personal experience in the form of a memoir. Consideration of the reaction to two specific incidents involving narrative memoirs that were later proven to be largely, or wholly, untrue shows how much the repercussions can vary when the fallacies are revealed.In 2008, writer Margaret Seltzer decided that the story of a mixed ethnicity, Native American foster child trying to survive the gang culture of South Central Los Angeles was a story that needed to be told. Unfortunately, she chose to recount that story in the form of a memoir, adopting the pseudonym Margaret B. Jones so that she could not readily be identified, to tell the tale in her book Love and Consequences. When it was revealed, by her sister, that she was actually white and grew up in a wealthy suburb of Los Angeles, Seltzer claimed that her desire was to give voice to legitimate concerns that were going unheard. This claim, though, ran counter to the persona she adopted for radio interviews while promoting the memoir, during which she chose to use a vernacular and carry herself in a way that she thought would lend authenticity to her story. In doing so, she did a disservice to those whose experiences she had appropriated, and within a week she suffered the consequences: all copies of the book were recalled by the publisher, and Seltzer has not had any published works since that time.Prior to Seltzer, author James Frey had also experienced the highs and lows of writing a successful memoir that was not completely based in fact. Be-fore his tale of the dark depths of addiction and the winding road to recovery, A Million Little Pieces, landed him at the top of The New York Times best-seller list for fifteen weeks in 2005, Frey and his editors notions of what should be considered a memoir were quite loose. Everything came tumbling down when Freys book was exposed as containing a number of fabrications, and just as quickly as Frey rose to prominence, he became a media pariah. Frey claimed that he had never represented A Million Little Pieces as anything other than a memoir and that his embellishment of events was within the bounds of what is considered acceptable as a memoir within the literary world. His time in the media spotlight tends to belie his claim, as it saw him embrace the fraudulent persona he had created for himself in his book. In recent years, the view of the publishing world and the media toward Frey has softened, and he later returned to the best-seller list with his fictional work, Bright Shiny Morning.Q.
