Final answer:
The use of 'para' to indicate a substitution or exchange is false; in English, phrases like 'for,' 'in exchange for,' or 'as a substitute for' serve this purpose.
Step-by-step explanation:
The statement “PARA is used to show a substitution or exchange” is false. In English, 'para' is not typically used to indicate a substitution or exchange. Instead, the word 'para' might be encountered in other languages, such as Spanish, where it can have a variety of meanings, including 'for', 'to', 'in order to', or 'toward' which are related to purpose or direction rather than substitution. In English, phrases like “for”, “in exchange for” or “as a substitute for” are commonly used to indicate substitution or exchange.
