I have a question on the choice between synonyms 'solution' vs. 'decision'. Is there any guideline to choose 'solution' rather than a 'decision' and vice versa?
Another question is on the verb to accompany solution/decision. Is it correct to say:
'make decision' (can I use 'take' here?)
'take solution' (can I use 'make' here? or the sence will change drasically into preparing a sort of liquid?)
What is better: "design solution/decision"?
A decision is simply what people will do (after discussion/thinking about it). It may or may not solve the issue. It may be a bad decision, or the decision may be to wait longer before doing anything.
A solution will solve a problem.
Make a decision -- most common. You may find "arrive at our decision."
Provide a solution.
Arrive at a solution.
Find a solution.
Determine a solution.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
