Identify the reason of unacceptable paraphrase in the 2nd paragraph. 1st Para: Here’s the original text, from page 1 of Lizzie Borden:
A Case Book of Family and Crime in the 1890s by Joyce Williams
The koala bear of Australia is a living “Teddy Bear.” Its thick coat of
gray fur is just as soft as the beloved toy. The koala has a large
head, big ears and small, dark eyes that look at you without
expression. Its nose, as black as patent leather, seems too big for
the rest of its face. The koala is a gentle little animal. It is almost
defenseless. Only its color protects it from enemies. The koala
makes no nest. It just sits in the forked branches of a tree. Unlike a
bird, it cannot balance itself with its tail—because it has no tail. It
likes gum trees the best because it loves entirely on the leaves of
the tree. Sometimes the supply of its special diet is used up. The
koala, rather than seek food elsewhere, will stay in its own area
and starve to death.
2nd Para: Here’s acceptable paraphrase.
The koala bear lives in Australia. It is really a “Teddy Bear” that is
alive. It has thick gray fur that feels as soft as that of the toy bear.
The koala has special features: big head, large ears, and little, dark
eyes without expression. As black as shiny leather, the koala’s nose
appears to be too large for his face. A gentle small animal, the koala
has only one way to defend itself from its enemies. Its color is itsonly protection. Making no nest, the koala just sits where branches
fork in a tree. Without a tail, the koala cannot keep itself balanced
like a bird. The koala eats only the leaves of gum trees which it likes
best. If all of its special food is eaten, the koala will not look for food
outside its own area. It will remain where it is and die of starvation.

The paraphrase in the second paragraph is unacceptable because it represents plagiarism.

Explanation:

A paraphrase occurs when the author of a text rewrites a sentence in another text, modifying the words but keeping the meaning. When a paraphrase is made, it is important that references to the author and the original text are made so that the paraphrase does not become plagiarism.

In the second paragraph shown in the question above, we have an example of plagiarism, since the author repeated complete sentences from the first paragraph, changing only the order in which they are established. Furthermore, he did not present the references to the original author of the sentences, thus being a case of plagiarism.

It is important to point out that plagiarism occurs when a text is copied in its entirety and references to the author are not presented.

the illustration   that would give a reader a clear understanding of the text is a picture of men constructing the frame of a building.the frame is made of iron bars. the text describes the job of blacksmiths'. these were very organised and they had different names: "the driver" and "the heater". the text describes the way in which these men worked ; they worked iron pieces as if they were playing a sport. in fact, the text wants to show the men's skills. the text also puts some emphasis on the use of '' rivets'' in construction. this kind of nails were not always used in the construction of manhattan.

some examples:

"and with an underhand toss he hurled the smoking rivet straight at the catcher, who caught it in mid-air in his catching can." men's skills

"when the driver was ready for a new " the emphasis on the rivet ( special nail used in construction).

" it against a beam to remove any cinders, and jammed it into the waiting hole. " the emphasis on the rivet.
