Subject : Science and Technology(8 December 2023)

1. Consider the following statements:

1. Gene therapy is an artificial method that introduces DNA into the cells of the human body.
2. CRISPR/Cas9 technology has the potential to revolutionise the treatment of many paediatric conditions.

How many of the statements given above are correct?

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

Answer: (C)

Explanation: Gene therapy is a technique that involves replacing defective genes with healthy genes to treat genetic disorders. It is an artificial method which allows entry of DNA into the cells of the human body. The first gene therapy was successfully conducted in the year 1989. Hence, statement 1 is correct CRISPR/Cas9 is a gene editing technology that allows DNA to be altered with great precision. This technology is still under development, but it has the potential to make significant advances in the treatment of many pediatric conditions. CRISPR/Cas9 can be used to treat a variety of pediatric conditions, including genetic disorders, cancer, immunodeficiency, and more. Hence, statement 2 is correct.


2. It is a technology where machines learn to perform tasks rather than simply completing calculations input by human users. Its early applications included machines that could play games such as checkers and chess, and programs that could reproduce language. This technology refers to the ability of computers or computer-controlled robots to perform tasks that are normally performed by humans.

The above passage explains which of the following techniques?

(a) Artificial intelligence
(b) Machine learning
(c) Neural network
(d) Deep learning

Answer: (A)

Explanation: The passage describing Artificial intelligence (AI). It is a vast field of computer science that focuses on creating intelligent machines capable of performing tasks typically requiring human intelligence. The early applications of AI, as mentioned in the passage, included game-playing programs and language translation systems. However, AI has now become much more sophisticated and is used in a wide variety of applications.

4. Consider the following statements:

1. Currently, Over-the-Top platforms and portals in India are regulated by the Information Technology Act, 2002.
2. There is immense potential for implementing Internet of Things in the Indian agricultural scenario.
3. Deep web websites can be accessed with the help of Tor browser. 4. Srikrishna Committee was entrusted with the task of drafting a data protection law for India.

How many of the above statements are correct?

(a) Only one
(b) Only two
(c) Only three
(d) All four

Answer: (C)

Explanation: "Over-the-top" (OTT) media service refers to an online platform that makes streaming media available as an independent product. The Information Technology Act, 2002 does not contain any specific rules or guidelines for over-the-top platforms and portals. For this reason, there is often controversy regarding the content available on these platforms. The government recently proposed a new policy to regulate over-the-top platforms and portals. Under this policy, more strict rules and guidelines will be implemented regarding the content available on these platforms. Hence statement 1 is not correct.
Many improvements can be made to the Indian agricultural landscape by using the Internet of Things (IoT). For example, IoT can be used in crop production, water management, and animal husbandry. Hence statement 2 is correct.
Tor Browser is an open-source web browser that uses encryption to hide a user's identity and location. This is necessary to access the Deep Web and Dark Web as these websites are separate from the public Internet. Hence statement 3 is correct.
Srikrishna Committee was appointed to prepare a data protection law for India. The committee had submitted its report in 2018. Hence statement 4 is correct.


5. Consider the following pairs in the Indian context:

(Act) (Year)
1. Patent Act 1970
2. Trademark Act 1999
3. Copyright Act 1957

How many of the above pairs are not correct?

(a) Only one
(b) Only two
(c) All three
(d) None

Answer: (D)

Explanation: The Indian Patent Act is the law relating to patents in India. This act was passed in 1970. Hence pair 1 is correct.
The Indian Trademark Act is the law relating to trademarks in India. This act was passed in 1999. Hence pair 2 is correct. The Indian Copyright Act is the law relating to copyright in India. This act was passed in 1957. Hence pair 3 is correct.
