What five conditions must be present for an exchange?
I'm trying to understand the requirements for an exchange to occur. Specifically, I want to know the five necessary conditions that must be present for an exchange to take place.
Does present mean past or future?
I don't understand this question. Could you please assist me in answering it?
Does is past or present?
Excuse me, could you please clarify for me? The sentence 'Does is past or present?' seems a bit confusing. Are you asking about the verb 'does' and whether it belongs to the past or present tense? If so, I would like to point out that 'does' is actually an auxiliary verb that is used to form the present tense of the verb 'to do' in the third person singular form. For example, 'He does his homework every day.' Here, 'does' is clearly in the present tense. Could you perhaps elaborate on your question if I've misunderstood your inquiry?
