Question

You are thirsty and decide to have an iced tea. your thirst is a​ ________ and your choice of iced tea is a​ ________.

Answer 1

A. ​demand; want  
Let's look at the 3 terms used in this question 
demand - Something or someone requiring attention. 
need - Something that's is required in order to live. 
want - Something that's desired, but not required.  
Now you're thirsty and you pick iced tea. It's pretty obvious that thirst isn't a "need", nor is iced tea, you could have picked a lot of different substances to get rid of your thirst such as water, milk, or some other beverage. And it's pretty obvious that thirst doesn't "want" to exist. But it can demand your attention. So with that in mind, let's look at the options.  
a. ​demand; want 
* This pretty much hits the target. Your thirst "demands" attention, and you
"want" to drink iced tea. So this is the correct choice. 
 b. ​want; demand
 * A bit reversed here. Do you "want" to be thirsty? And if so, why are you getting rid of the thirst by drinking? So this is a bad choice.  
c. ​want; need 
* Iced tea is never a "need", so this is obviously a bad choice.  
d. ​need; demand 
* You don't have a need for thirst. And if you did, why are you drinking to get rid of it? So another bad choice.  
e. ​need; want 
* Just repeat "d" above. If you need thirst, why drink? So a bad choice.

Answer 2

d. ​need; demand

Thirst is a need rather than a demand or want, since we need regular fluid intake for our survival and optimum functioning. A choice of ice tea is a demand rather than a want or need because a want or need does not involve the ability to afford the ice tea. Demand on the other hand involves the desire and ability to buy a product.
