Question
1. Instead of simply digitizing a paper-based process
for registering and operating drones, India has formulated an all-digital process. 2. Research shows that 56% of Indian shoppers ditch there shopping carts after loading. 3. Despite persistent requests from government officials and research institutions, China has not provided samples of the danger virus. In the question below, three statements are given which may or may not contain an error. Choose the option that provides the correct combination of sentences that are grammatically correct.ÂSolution
(a) is the right answer as only (1) is grammatically correct. In (2), we need to replace THERE with THEIR, as we need the possessive pronoun THEIR instead of an adverb as it is being used to refer to a noun (Indian Shoppers). In (3), we need to replace the noun DANGER with the adjective DANGEROUS as it is modifying the noun VIRUS. Thus, (a) is the right answer.Â
