GATE EC 2021 Set 1 — Question 7

Let's analyze each statement based on the passage:(i) "Nowadays, computers are present in almost all places." The passage states: "Computers are ubiquitous. They are used to improve efficiency in almost all fields from agriculture to space exploration." Ubiquitous means present everywhere. This statement is correct.(ii) "Computers cannot be used for solving problems in engineering." The passage states: "They are used to improve efficiency in almost all fields from agriculture and space exploration." Engineering is a field where efficiency is improved by computers. This statement contradicts the passage and is incorrect.(iii) "For humans, there are both positive and negative effects of using computers." The passage states: "AI enables computers to learn, given enough training data." (positive) and "For humans, sitting in front of a computer for long hours can lead to health issues." (negative). This statement is correct.(iv) "Artificial intelligence can be done without data." The passage states: "AI enables computers to learn, given enough training data." This implies data is necessary for AI. This statement is incorrect.Therefore, the correct deductions are (i) and (iii).The final answer is $\boxed{D}$
