Text 1Recent studies on exoplanets have challenged the conventional understanding that gas giants primarily form far from their host stars. In a 2022 analysis of data from the Kepler Space Telescope, researchers identified several gas giants in close proximity to their stars, contradicting the traditional model of planetary formation.Text 2Researchers who have charted the formation of gas giant planets acknowledge that their analysis relies on indirect observational methods, and some scientists argue that alternative explanations, such as planetary migration, could account for the observed distribution of gas giants. While the data suggests the existence of gas giants in close proximity to stars, critics emphasize the need for caution in interpreting these findings and advocate for further observational techniques to validate the conclusions.9Mark for ReviewCross out answer choices you think are wrong.ABCWhich choice best describes how Text 1 and Text 2 relate to each other?AText 1 discusses recent findings challenging established ideas about gas giant formation without favoring any specific explanation, whereas Text 2 raises concerns about the methodology behind those findings.BText 1 argues that the traditional model of gas giant formation is outdated based on recent research, whereas Text 2 proposes a modified version of the traditional model that accommodates the new observations.CText 1 outlines a study on gas giants and addresses criticisms of its methodology, whereas Text 2 provides additional evidence supporting the findings of traditional models.DText 1 presents new observations about gas giants and introduces potential discrepancies, while Text 2 scrutinizes the methodology and suggests alternative explanations for the observed data.

Which planets are the "outer" planets- sometimes called the Gas Giants?

Look at the following statement from the Article:Astronomers have discovered thousands of planets outside our solar system, but as of March 2017 most of those found were not within the habitable zones of their stars and only a handful of them were approximately the size of Earth.Why did the author include this information?A.To demonstrate why the researchers involved in the discovery of the TRAPPIST-1 system need to study the chemical compositions and atmospheres of seven planetsB.To point out that while the TRAPPIST-1 system features a dwarf star, the rocky planets in the system are all within a habitable zoneC.To emphasize that it is unusual for astronomers to discover planets like those found orbiting TRAPPIST-1D.To question whether the three Earth-size planets near TRAPPIST-1 are truly orbiting within the habitable zone of such a compact star system

4.Question 4The terrestrial planets appear to have taken much longer to finally assemble than the gas giants did. Which of the following statements about these timescale is NOT true?1 pointOne reason that the gas giant formation timescale is thought to be so fast is that we do not observe stars to have gas around them after they are ~3 Myr oldWe can learn about the timescale of terrestrial planet differentiation by looking at isotopic ratios of hafnium and tungsten.Oligarchs form very quickly through runaway growth but because they are gravitationally isolated it takes a long time for them to assemble into larger bodies.Mars differentiated quickly, so tungsten-182, the radioactive decay product of hafnium, is abundant in Martian meteorites.All of these statements are trueGrowth of the terrestrial planets was slowed by the rapid growth of the gas giants, which caused oligarchs to have have velocities and break apart

Which statement from the Article best supports the notion that researchers are encouraged by the discovery of the TRAPPIST-1 star system?A."With this amazing system, we know that there must be many more potentially life-bearing worlds out there just waiting to be found," she said.B."Every now and then, you would see another planet, maybe about as big as twice the moon in the sky, depending on which planet you're on and which planet you look at."C.But the planets' proximity to TRAPPIST-1 doesn't mean they get exceedingly hot; the star, which is 200 times dimmer than our sun, is also much cooler.D.The planets circle tightly around a dim dwarf star called TRAPPIST-1, which is about the size of Jupiter.SUBMITExtras© 2024 Achieve3000 Inc. and its licensors.All Rights Reserved.

The reader can infer from the Article that __________.A.The location of a habitable zone in a star system must depend, in part, on the temperature of the central star around which the planets orbit.B.Planets that only take 20 Earth-days to orbit a star would be moving too quickly to support life, even if they had liquid water.C.Sending astrophysicists to investigate the TRAPPIST-1 system is the next logical step in the research of the planets there.D.Thomas Zurbuchen and Sara Seager disagree about the likelihood of finding an Earth-size planet that is truly habitable.SUBMITExtras
