Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.1. The detection of gravitational waves opened a new window into understanding the universe, allowing astronomers to observe phenomena that were previously invisible.2. Despite its significance, this discovery also posed questions about the sustainability of space exploration and its environmental impact on Earth.3. This breakthrough led to a deeper understanding of black holes and neutron stars, shedding light on some of the most mysterious objects in the cosmos.4. One of the most remarkable achievements in recent years has been the direct observation of gravitational waves, confirming a major prediction of Einstein's theory of relativity.5. As a result, scientists were able to provide more evidence supporting the Big Bang theory, offering insights into the early moments of the universe.

Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out. Choose its number as your answer and key it in.As a result, discoveries can be made long after a telescope has been decommissioned.In doing so, the Kepler telescope has made “exoplanet research” one of the busiest areas of astronomy.Some of these worlds are far enough from their stars for liquid water to exist on the surface, meaning that these worlds would possibly be hospitable to life.Since then, it has spotted 2700 alien worlds.The Kepler telescope was launched into space in 2009 to look for extrasolar planets, those that circle stars other than the sun.

The lure of human space travel is undeniable. We’ve allgrown up on endless types of entertainment set in thefuture that portray adventures on distant planets. Imagineyourself as an astronaut, a part of the first manned mission toMars. Beyond that, there are generations of people who havebeen working to make space and space travel look cool, eveninevitable. But high aspirations and romance aside, we needto face the harsh realities. Our notions about the inevitabilityand wonder of human space travel need to be checked, andany plans need to be reconsidered. Some of the best reasons tocurtail space exploration come down to economics, human cost,and technology.1Should robots lead the journey to outer space?This writer says yes.Let Robots Take tothe StarsArgument by Eiren CaffallANALYZE ARGUMENTAnnotate: In paragraph 1, markthe author’s central claim andmark the reasons the author willuse to support the claim.Interpret: What will the author’sargument be?

To get humans to Mars,it would take $1 trillion over a 25-year period. Obviously, nosingle government would want to take on that kind of funding.A Mars mission would require international cooperation at asignificant cost to each partner nation. A Mars mission mightfoster international cooperation, but it would consume fundsthat could be used for other things.Some people suggest that the only way to get to Mars wouldbe with the help of private companies. Because of this, thespace exploration industry is made up not only of governmentagencies but also private companies headed by dreamersand people interested in profits over practicality. But theseorganizations are often badly managed. They don’t work for thegovernment, so accountability could be a problem. Even well-run companies are unlikely to have enough money to launcha Mars mission on their own. There are some experts who saythat it wouldn’t be possible to launch a mission to Mars withoutfunding from commercials that would run during coverage ofthe project. That would turn a scientific mission into a realitytelevision show. Would you want to trust a scientific mission tothe people who run reality TV?Space Travel Could Harm OurPolluted WorldThe risks of space exploration could be grave for a planetalready plagued by pollution. There is an extra result of spacetravel: black carbon from rocket exhaust that’s deposited inthe outer atmosphere. The launch of a suborbital tourist craftis said to produce less carbon emissions than a standard flightfrom New York to London. However, once the rocket is abovethe atmosphere, the black carbon it releases can be prettydamaging. Try to imagine the black smoke from a diesel trucksitting above the sky. With no weather to wash it into theoceans, black carbon can stay put for up to ten years.Many space boosters are suggesting that being able toleave our planet once it’s exhausted of resources is a priority.They seem to be proposing that we have some sort of Planet B.Somehow they think that a colony on Mars or the moon couldtake the pressure off our world. Many of these people planningto profit from two things at once are also fans of the dubioustechnology of geoengineering.

Former astronaut Mark Watney believes that although there is no definitive timeline, it's inevitable that humans will eventually need to adapt to living on Mars or in other extraterrestrial environments. This belief ______ his advocacy for continued research missions to Mars.Which choice best completes the text with the most logical and precise word or phrase?Choose Your AnswerPreviousNextA.assertsB.anticipatesC.refutesD.underscores
