Wide Awake Trivia Quiz

Answer: Carla

Clue C tells us that Carla called first. The call times range on the hour from 12:00 a.m. to 4:00 a.m. The first time available is 12:00 a.m. (midnight). This was just simply reading the clues!

Answer: Mary

Clue E tells us that Mary called before the coffee-drinker. (Coffee contains caffeine).
Clue A tells us that the coffee-drinker called at some point before Fiona.
Therefore, Mary called before Fiona.

Answer: Mary

Clue E tells us that Mary called before the coffee-drinker (coffee contains caffeine).
Clues A and B together tell us that the coffee-drinker called at some point before Fiona AND before the late exerciser.

So Mary has to be first or second since she called before three other people (the coffee-drinker, Fiona, and the late exerciser).
Clue E tells us that Carla is first (midnight).
Therefore, Mary must be second, so she called at 1:00am.

Answer: worry

Carla called before Mary (See Q1 explanation).
Mary called before three other women, as determined in question 3: a coffee-drinker, Fiona, and the late exerciser.

Clue E tells us that Mary called before someone worried about an upcoming trial. That has to be Fiona. Let's hope her trial goes well!


[In other words:
Mary called before the late exerciser and the coffee-drinker (see Q3 explanation) and Clue E tells us she called before the worrier.
So, Fiona did one of those three things.
Clue A tells us that Fiona is not the late exerciser.
Clues A & B together tell us that Fiona cannot be the coffee-drinker. The coffee-drinker called BEFORE the late exerciser (clue B), but Fiona called AFTER the late exerciser (clue A).
That leaves the worrier, who must be Fiona. I told her to trust in her attorney!]

Answer: snoring spouse

Clue D tells us that Carla was not kept awake by hunger.
Question 4 tells us that worry is what kept Fiona awake.
Carla called first (question 1 or clue E), which means she is neither the coffee-drinker nor the exerciser, who called sometime after Mary (see Question 3 or review clues E, A, & B).

That leaves only the snoring spouse for Carla. I suggested a visit with a specialist; it could be apnea!

Answer: Mary

We determined in question 5 that Carla was troubled by the snoring spouse.
We determined in question 4 that Fiona was too worried about her trial to sleep.
We know that neither caffeine nor late exercise kept Mary awake, as she called before either of these sufferers, as determined in question 3.

That means that hunger kept Mary wide awake. I told her if she's too hungry to sleep she should change her eating plan.

Answer: Barbara

We've already determined...
... hunger kept Mary awake. (question 6) (Also clue E eliminates her).
... a snoring spouse kept Carla awake. (question 5) (also Clues C & E eliminate her).
... worry kept Fiona awake. (question 4)

Clue F tells us Edna did not consume any caffeine.
Therefore, Barbara, the only person left, must be the wide-awake coffee drinker.

Answer: Barbara

We already know...
... Carla rang first, at 12:00 a.m. (clue C), and was kept awake by snoring (question 5).
... Mary rang second, at 1:00 a.m. (question 3), and was kept awake by hunger (question 6).

The caffeine-drinker called before two other people: the late exerciser (clue B) and also before Fiona (clue A). That can only be 2:00am since midnight and 1:00am are taken. We've already determined that Barbara drank the caffeine (question 7), so she's the 2-o'clock caller!

Answer: Edna

Clues A & B together tell us that the late exerciser called after the coffee maven but before Fiona.
Questions 7 & 8 told us that the coffee maven, Barbara, called at 2:00a.m.
The only times left are 3:00 a.m. and 4:00 a.m., so the only time that fits for the late exerciser is 3:00 a.m..

We've already determined that...
... Fiona suffered from worry
... Carla's spouse snored
... Barbara drank too much coffee
... Mary was hungry from dieting

So the only person left is Edna!

Answer: Fiona

Fiona, worried about her upcoming trial (Question 4), must be last @ 4:00 a.m. because ...
... she called after the late-exercising Edna @ 3:00 a.m. (Question 9),
... who called after coffee-guzzling Barbara @ 2:00 a.m. (Questions 7 & 8),
... who called after hungry Mary @ 1:00 a.m. (Questions 3 & 6),
... who called after Carla, who by midnight could no longer bear her husband's snores! (Questions 1 & 5)

And with that, we have all five friends, the time they called, and why! Now I can get some sleep myself!
