CAT Paragraph Summary Question 8

Question 8:

The passage given below is followed by four summaries. Choose the option that best captures the author’s position.

Artificial embryo twinning is a relatively low-tech way to make clones. As the name suggests, this technique mimics the natural process that creates identical twins. In nature, twins form very early in development when the embryo splits in two. Twinning happens in the first days after egg and sperm join, while the embryo is made of just a small number of unspecialized cells. Each half of the embryo continues dividing on its own, ultimately developing into separate, complete individuals. Since they developed from the same fertilized egg, the resulting individuals are genetically identical.

  1. Artificial embryo twinning is low-tech and mimetic of the natural development of genetically identical twins from the embryo after fertilization.
  2. Artificial embryo twinning is low-tech unlike the natural development of identical twins from the embryo after fertilization.
  3. Artificial embryo twinning is just like the natural development of twins, where during fertilization twins are formed.
  4. Artificial embryo twinning is low-tech and is close to the natural development of twins where the embryo splits into two identical twins.
Option: 1

This is a slightly tricky question in which we have to pick the options after carefully comparing them with the others. The first sentence says that artificial embryo twinning is low-tech. The second sentence says that it mimics the natural process that creates identical twins. Option 1 very much captures the key ideas. In option 2, the word ‘unlike’ shows dissimilarity, but the passage focuses on similarity, not dissimilarity. Option 2 goes out. Option 3 says twins are formed during fertilization, but the passage says that the twins are formed after fertilization. Option 4 is close to 1 but does not clearly specify the exact time when the embryo splits into two. Moreover, the passage says mimics, while option 4 says ‘close to’, which is a slight distortion of the facts as given in the passage.
