37. Following is the passage which is followed by 4 questions based on its content. After reading a passage , choose the best answer to each question.

If a supernova (the explosion of a massive star) triggered star formation from dense clouds of gas and dust, and if the most massive star to be formed from the cloud evolved into a supernova and triggered a new round of star formation, and so on, then a chain of star -forming regions would result. If many such chains were created in a differentially rotating galaxy,the distribution of stars would resemble the observed distribution in a spiral galaxy. This line of reasoning underlies an exciting new theory of spiral-galaxy structure.

A computer simulation theory has reproduced the appearance of many spiral galaxies without assuming an underlying density wave, the hallmark of the most widely accepted theory of large-scale structure of spiral galaxies. That theory maintains that a density wave of spiral form sweeps through the central plane of galaxy, compressing clouds of gas and dust, which collapse into stars that form a spiral pattern.

The primary purpose of the passage is to :

• Describe what results when a supernova triggers the creation of chains of star-forming regions.
• Propose a modification in the most widely accepted theory of spiral-galaxy structure.
• Compare and contrast the roles of clouds of gas and dust in two theories of spiral-galaxy structure.
• Describe a new theory of spiral-galaxy structure and contrast it with the most widely accepted theory. (Answer)

38. The passage implies that, according to the new theory of spiral-galaxy structure, a spiral galaxy can be created by supernovas when the supernovas are:
• producing an underlying density wave
• affected by a density wave of spiral form
• located in a differentially rotating galaxy (Answer)
• distributed in spiral pattern

39. Which of the following, if true, would most discredit the new theory as described in the passage?
• The exact mechanism by which a star becomes a supernova is not yet completely known and may even differ for different stars.
• The most massive stars formed from supernova explosions are unlikely to evolve into supernovas. (Answer)
• Computer simulations of supernovas provide a poor picture of what occurs just before a supernova explosion,
• A density wave cannot compress clouds of gas and dust to density high enough to create a star.

40. The author's attitude toward the new theory of spiral- galaxy structure can best described as :
• euphoric
• concerned
• critical

there are many approaches for this sum. the least confusing one is this:

let w be the efficiency of worker i.e., 1/ no. of days one worker takes to complete the work.

and b is the efficiency for boy.

Now write the efficiency equations:

2w + 7b = 1/14 => use 1/14, not 14 since we are using efficiency equations.
3w + 8b = 1/11

solving these equations, finding w, b substitute it in 1w + 1b => you will get 1/7 => i worker and 1 boy will take 7 days

but the question was for 3 times the work. so obviously they'll take three times the days = 21 days.

i hope it is clear 😀

I think after solving the equations and getting w and b, we should find 8w+6b, and not 1w+1b..

Solving gives w=1/77 and b=1/154.
We need to find how many days 8 workers and 6 boys need to complete 3 times the work..

So, 8w+6b = [8/77 + 6/154] = 22/154 = 1/7
And, 1/7*21 = 3. so, they need 21 days to complete 3 times the work. 😀

sorry that was a typo... after solving for w, b substitue in 8w+6b 😀 like what ss said...
