Question 1

Five houses in a row are painted red, blue, green, yellow, and white. The green house is immediately to the left of the white house. The red house is first. The blue house is adjacent to the green house. Which house is blue?

Accepted Answer

Third

Answer

Red is first; green-white must be consecutive, and blue is adjacent to green — placing green 3rd, white 4th, and blue 2nd or 4th; since white is 4th, blue must be 3rd.

Question 2

If all Bloops are Razzles, and all Razzles are Lazzles, which conclusion must be true?

All Bloops are Lazzles

Answer

Transitivity of universal affirmatives: Bloops ⊂ Razzles ⊂ Lazzles, so all Bloops are Lazzles.
