Today, the steel beams and girders of the city's skyscrapers are bolted together with special steel bolts and welded together. compared with riveting, these connections are stronger, more quickly made, and require fewer men to accomplish.

which choice is the best paraphrase of the text?

a. steel beams and girders in modern-day city skyscrapers have stronger connections and are put together more quickly and with fewer workers than connections formed by riveting.

b. steel beams and girders in today’s skyscrapers are constructed with specially made steel bolts. then, they are welded together. these modern-day connections are put together more quickly and by fewer workers than the ones made in the past by riveting. they are also stronger.

c. today, the steel beams and girders of the city's skyscrapers are bolted together with special steel bolts and welded together. compared with riveting, these connections are stronger, more quickly made, and require fewer men to accomplish.

d. today’s skyscrapers are built using steel bolts that are specially made for skyscraper construction. these bolts are welded together and create stronger connections than those made by riveting.

The answer is b.

Step-by-step explanation:

The best paraphrase text is the one which has different sentence structures but does not miss any important information. All other options are missing some important features.

Lets analyse the important points of the paragraph and then check individual answers. Following are important points.

1. steel beams and griders of skyscrapers

2. Special steel bolts which are welded together.

3. comparison with Riveting

4. Strong, quickly made and require lesser men

Now lets check individual answers.

(a) it cannot be the answer because it misses the welded part.

(b) it is the right answer because it has all the above mentioned important information. None is missing.

(c) it is the same as the original text thus it is not paraphrased at all.

(d) It misses the information of less men requirement for making connections.

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
