Environment And Sustainable Development — Economics STD 12 Humanities & Commerce — Question

Read this excerpt of a news item from a daily newspaper describing something that is now becoming increasingly common.
"On a morning, a few minutes before 7A.M., Greeshma sat in front of her computer with her headset on and said in accented English 'Hello, Daniella'. Second later, she gets the reply, 'Hello, Greeshma'. The two chatted excitedly before Greeshma said that we will work on pronouns today'. Nothing unusual about this that except that Greeshma, 22, was in Kochi and her student Daniella, 13, was at her home in Malibu, California. Using a simulated whiteboard on their computers, connected by the Internet, and a copy of Daniella's textbook in front of Greeshma, she guides the teenager through the intricacies of nouns, adjectives and verbs. Greeshma, who grew up speaking Malayalam, was teaching Daniella English grammar, comprehension and writing."
