New Project RC Butler 2019 - Practice 2 RC Passages Everyday
Passage # 296, Date : 28-Aug-2019
This post is a part of New Project RC Butler 2019. Click here for Details


M31, M32, and M33 are members of the Local Group, an assemblage of more than 54 galaxies in the neighborhood of the Milky Way, the galaxy which contains our solar system. Like the Milky Way, M31 and M33 are spiral galaxies, whereas M32 is a dwarf elliptical galaxy. Of the three, M31, also known as the Andromeda Galaxy, is the largest, with a mass that has been estimated in recent studies to be equal to or greater than that of the Milky Way. Comprised primarily of older faint stars, M32 is a substantially smaller galaxy and a satellite of Andromeda. M33, known as the Triangulum Galaxy, is more distant and less massive than Andromeda and is believed to have collided with that galaxy in the past.

The attributes of these four galaxies may reflect their past interactions and are likely to shape future encounters. For example, astronomers are not currently sure how M32's compact ellipsoid shape took form, but they suspect that M32 may have had a spiral shape earlier that was transformed by a tidal field from Andromeda into its current elliptical shape. Meanwhile, Triangulum and Andromeda are connected by a stream of hydrogen and stars, which is evidence that the two galaxies have interacted in the past between 2 and 8 billion years ago. Finally, among the trio M31, M33 and the Milky, every pair is potentially on a collision course compelled by gravity. Triangulum might be ripped apart and absorbed by M31, it might collide with the Milky Way before the latter has any violent interaction with Andromeda, or it might participate in the collision between the Milky Way and the Andromeda Galaxy, which is expected to occur in about 4 billion years.


1. According to the passage, the difference in shape between M32 and the other galaxies discussed can be explained with reference to which of the following factors?

A. Mass
B. Speed of rotation
C. A stream of hydrogen and stars
D. Collision with another galaxy
E. The tidal field of a nearby galaxy



2. Which of the following best describes the purpose of the second paragraph of the passage?

A. To suggest a relationship between the characteristics of the galaxies in question and the events of their past and future
B. To compare how M31, M32, M33, and the Milky Way were formed
C. To provide a comprehensive theory of the differences of the four members of the Local Group
D. To contrast the characteristics of the four galaxies discussed with the characteristics of other galaxies that are members of the Local Group
E. To introduce facts that contradict popular assumptions about M31, M32, M33, and the Milky Way



3. The author's reference in the highlighted text to the stream of hydrogen and stars serves primarily to

A. provide support for the idea that galaxies' structures reflect past interactions
B. suggest that Triangulum and Andromeda will collide in the future
C. provide an explanation for the variations in shape of the galaxies discussed
D. emphasize how poorly understood Triangulum's future course is
E. illustrate the functional equivalence of the Triangulum and Andromeda

Para 1 Summary – Author refers to three galaxies named M31, M32 and M33 as part of local group, which has 54 galaxies. M31 and M33 are spiral in shape and M32 a dwarf s elliptical. M31 is largest among the three to which M32 is a satellite. Finally, M33 might have collided with M31 in the past.

Para 2 Summary – In the para author presents how the three galaxies might have had interacted in the past. Astronomers suspect M32’s shape to have transformed from spiral to elliptical by M31’s tidal field. M31 and M33 are connected by a stream of hydrogen and stars. Lastly, author mentions that M31 M33 and Milky as pairs might collide in one or the other way.

Summary – Author talks about four galaxies and discussed about their size weight and much believed past and finally puts down astronomers’ suspicion about three galaxies’ future collision.

1. According to the passage, the difference in shape between M32 and the other galaxies discussed can be explained with reference to which of the following factors?

A. Mass – WRONG.
B. Speed of rotation – WRONG.
C. A stream of hydrogen and stars – WRONG.
D. Collision with another galaxy – WRONG.
E. The tidal field of a nearby galaxy – CORRECT. Only this option is right. Refer para 1.

2. Which of the following best describes the purpose of the second paragraph of the passage?

A. To suggest a relationship between the characteristics of the galaxies in question and the events of their past and future – CORRECT. Exactly that’s how para 2 is constructed after initial introduction in para 1.
B. To compare how M31, M32, M33, and the Milky Way were formed – WRONG. Formation is not discussed anywhere in the passage.
C. To provide a comprehensive theory of the differences of the four members of the Local Group – WRONG. Differences are presented but no comprehensive theory is presented.
D. To contrast the characteristics of the four galaxies discussed with the characteristics of other galaxies that are members of the Local Group – WRONG. Irrelevant.
E. To introduce facts that contradict popular assumptions about M31, M32, M33, and the Milky Way – WRONG. No contradiction is mentioned by author.

3. The author's reference in the highlighted text to the stream of hydrogen and stars serves primarily to

A. provide support for the idea that galaxies' structures reflect past interactions – CORRECT. The stream of hydrogen and stars is presented in the context of any possible past relationship between the two galaxies M31 and M33.
B. suggest that Triangulum and Andromeda will collide in the future – WRONG. Its a different context not this one.
C. provide an explanation for the variations in shape of the galaxies discussed – WRONG. Shape variations is of M32 not the M31 and M33.
D. emphasize how poorly understood Triangulum's future course is – WRONG. Irrelevant.
E. illustrate the functional equivalence of the Triangulum and Andromeda – WRONG. Irrelevant.

Got all correct in 6:22 minutes.

1. According to the passage, the difference in shape between M32 and the other galaxies discussed can be explained with reference to which of the following factors?

E. The tidal field of a nearby galaxy - Towards the middle of the second paragraph, we have the statement ".....M32......spiral shape ........ transformed by a tidal field from Andromeda". Hence, (E) is the right answer choice.

2. Which of the following best describes the purpose of the second paragraph of the passage?

A. To suggest a relationship between the characteristics of the galaxies in question and the events of their past and future - In the first sentence of the second paragraph, we have "The attributes of these four galaxies .....reflect their past interactions and.... likely to shape future encounters." Hence, (A) is the right answer.

3. The author's reference in the highlighted text to the stream of hydrogen and stars serves primarily to

A. provide support for the idea that galaxies' structures reflect past interactions - towards the middle of the second paragraph, we have "Triangulum and Andromeda....stream of hydrogen and stars,...evidence that the two galaxies have interacted in the past". Hence, (A) is the right answer choice.
