Question

A company is reviewing three employee training modules: Atlas, Beacon, and Cascade. Each module includes three sections: reading, practice, and assessment. In every module, one section is Introductory, one section is Standard, and one section is Advanced.
 
The following information is known:
 
• Exactly one module has an Introductory reading section.
 
• Exactly two modules have an Advanced practice section, and the remaining module has an Introductory practice section.
 
• Atlas and Cascade both have Standard reading sections.
 
Select for  True  a statement that must be true, and select for  False  a statement that must be false, based on the information provided. Make only two selections, one in each column.

Official Solution:

Atlas and Cascade both have Standard reading sections (point 3). Since exactly one module has an Introductory reading section (point 1), Beacon must have an Introductory reading section.
 
In every module, one section is Introductory, one is Standard, and one is Advanced. So  Beacon cannot have an Introductory practice section , because Beacon already has an Introductory reading section.
 
Therefore, the second statement (Beacon has an Introductory practice section) must be false.
 
Since exactly two modules have Advanced practice sections and Beacon cannot have Introductory practice,  Beacon must have an Advanced practice section .
 
So Beacon has:
 
• Reading: Introductory
 
• Practice: Advanced
 
• Assessment: Standard
 
The two possible distributions are:
 
 CASE 1: 
         Atlas   Beacon   Cascade       Reading   Standard   Introductory   Standard       Practice   Advanced   Advanced   Introductory       Assessment   Introductory   Standard   Advanced

CASE 2: 
         Atlas   Beacon   Cascade       Reading   Standard   Introductory   Standard       Practice   Introductory   Advanced   Advanced       Assessment   Advanced   Standard   Introductory

In both possible distributions,  Beacon has a Standard assessment section . Therefore, the fifth statement (Beacon has a Standard assessment section) must be true.
 
All other statements are not necessarily true or false.

Correct answer:

True  "Beacon has a Standard assessment section."

False  "Beacon has an Introductory practice section."
