There are two statements below an assertion (A) and a reason (R) about English for Specific Purposes. Mark the correct answer about them.

Assertion (A)

When designing an English for Specific Purposes (ESP) course, the first stage is to carry out a rigorous needs analysis of the target situation and only after that the organizational patterns in specific texts should be identified to specify the linguistics means by which they are signaled. After adding such patterns to specific register and lexical components, the course design is ready. Thus, there are just these three stages in ESP for Hutchinson and Waters (1987).

Reason (R)

Using the analogy of a tree, Hutchinson and Waters (1987) defined ESP as a language product whose root is English Language Teaching (ELT) and branches are English for Academic Purposes (EAP) and English for Occupational Purposes (EOP). Thus, the main point of ESP is to teach specialized vocabulary.
