It is true that all of the materials must be used at least once. Here's why you need N, hopefully this helps:

[3 Materials Needed] Center 1: (N) (T/W) (P) [ Must have 3 materials b/c you need P here - if it’s in C2 it needs to be in C1; and, P can only be used once. Cannot include G b/c you have P; if you have W, you need N. So W T cannot be a pair.]

[2 Materials Needed] Center 2: (N) (T/W) [N must be one of them for the reasons explained above - and you need T/W to fill the min of 2]

[2 or 3 Materials Needed] Center 3: (NW, NT, or T) and G [must include G, whichever material is not placed in Centers 1 and 2 above must be placed in Center 3. If that is W then you will need N; if that's T then N is optional]

The online tool provides options to change the time allocated. The time adjustment option is the clock icon to the left of the underline/highlight functions.

Thanks!

Nevermind! Misunderstood

#Help - what CC lesson is about denying a conditional statement?

Even though (B) looks like it is making the two groups (A and B) more similar, it actually isn’t making a difference. Because we do not know when groups A and B started in the first place, they could have also started at different times prior to the study. For example,

Previous Month:

A: 8:00 AM, produces 10 units

B: 11:00 AM, produces 20 units

Month of Study:

A: 8:00 AM, nutritious breakfast, 50 units (+40)

B: 11:00 AM, no nutritious breakfast, 20 units (+0)

Hope this helps!

#Help - Has anyone come across another question like this, regarding beliefs + false beliefs? Thanks in advance!

#Help - to confirm, it's just a coincidence that A is used to represent Beauty = Truth and A is used to represent Beauty?

To clarify the example, is this a correct interpretation of the problem?

A: Beauty

B: Best

C: Most Real

D: Most Truthful

E: A = D

F: C = B

A = D --> C = B

Assumption in answer: A = B
