Which of the following is most logically being conveyed by the argument above?

Directions: Answer the question based on the following passage.

English has become the Lingua Franca of the world. The countries where English was once considered to be a difficult language now promote it as the medium of education, thus adding to its acceptance all over the world. Earlier, on trips to various countries for work or pleasure, one would find it difficult to communicate with the natives. Now if you know how to read, write and speak English, you can travel to any part of the world and have no trouble talking to the local people.

(1) Incorrect. The option uses a generic 'education', instead of use of English as a medium of education and communication. 'Some countries' also makes the option restrictive. (2) Incorrect. 'Many eastern countries' makes the option very restrictive. (3) Correct. The conclusion is that English has become very popular in many parts of the world. English cannot be called a world language if its education is limited to only a few city schools in most countries, and only a small fraction of the local people is conversant with the language. It follows that schools across the world are using/ teaching English as a language. (4) Incorrect. The argument states that there is no difficulty in communicating in English. It doesn't say whether travelers rely on personal contacts (as against interpreters). (5) Incorrect. It cannot be stated with certainty. English language might be getting introduced in schools at varying levels across the world.
