Is Bob in a relationship with TERESA or SONIA?
Show Answer
Answer: TERESA.
Explanation:
Bob only likes words that can be typed using only the left hand on a standard QWERTY keyboard. The left-hand letters are:
Q W E R T A S D F G Z X C V B
Check the examples:
- BREAD = B R E A D → all left-hand letters → liked.
- BAGEL = B A G E L → L is a right-hand letter → disliked.
- TEA = T E A → all left → liked.
- COFFEE contains O (right) → disliked.
- WATER = W A T E R → all left → liked.
- SODA contains O (right) → disliked.
- SAX = S A X → all left → liked.
- DRUM contains U, M (right) → disliked.
- EDGE = E D G E → all left → liked.
- CHROME contains H, O, M (right) → disliked.
- SCARVES = S C A R V E S → all left → liked.
- HATS contains H (right) → disliked.
Finally, the two names: TERESA = T E R E S A (all left-hand letters) → Bob likes Teresa. SONIA = S O N I A (contains O, N, I — right-hand letters) → Bob would not like Sonia.
