Genre analysis in English for Specific Purposes (ESP) involves understanding the communicative purposes, schematic structures, and linguistic features specific to discourse communities. Regarding the characteristics of the "Academic Abstract" genre, mark T for true and F for false:

(__) An academic abstract typically follows the IMRaD structure (Introduction, Methods, Results, and Discussion) in a condensed form to provide a comprehensive overview of the study.
(__) The primary communicative purpose of an abstract is to persuade the reader to buy the product described in the text, using informal language and slang.
(__) Linguistic features of abstracts often include the use of the present perfect tense to refer to past research (Gap) and the simple past to describe the specific methods used in the current study.
(__) Abstracts are characterized by a high lexical density and nominalization, allowing for the packing of complex information into a limited word count.
