Thinking Skills Mock Test 20: 2027 NSW Selective Format

We have a chain of logic: If Dana does not eat breakfast, she will be hungry by mid-morning. If she is hungry by mid-morning, she cannot concentrate well in class.

So if Dana is hungry by mid-morning, then she cannot concentrate well.

Now check the options. Dana ate breakfast and concentrated well: possible. Dana ate breakfast and did not concentrate well: also possible, because the rule does not say breakfast guarantees good concentration. Dana did not eat breakfast and was hungry by mid-morning: possible, because that follows the rule. Dana was hungry by mid-morning and still concentrated well: not possible, because the second rule says hunger means she cannot concentrate well.

So the last option is the one that is not possible.

Both views show the oval on top. Across the two views, five of the cube's six faces are visible: oval (top), heart, rectangle, smiley face, and star. The sixth face — the bottom, directly opposite the oval — is never seen in either view.

Since options A, B, and C show faces that are already visible elsewhere on the cube, none of them can be the bottom face.

• A (heart): visible as the front in View 1. ✗
• B (smiley face): visible as the front in View 2. ✗
• C (star): visible on the right in View 2. ✗
• D (None of the above) ✓: the bottom is the unseen sixth face.
