B, C, E, F and H have different heights. B is taller than C but shorter than H. H is taller than E but shorter than F. E is taller than C but shorter than B. How many people are shorter than B?

Arrange everyone in a single vertical column from tallest to shortest based on the given clues and count those below B.
Arrange everyone in a single vertical column from tallest to shortest based on the given clues and count those below B.
Analyze the conditions
Conditions given: 1) B > C, 2) H > B, 3) F > H > E, 4) B > E > C. Combining these: F > H > B > E > C.
Establish the order
From the combined sequence F > H > B > E > C, we can clearly see the hierarchy of height.
Count shorter than B
Looking at the sequence, E and C are positioned below B. Thus, 2 people are shorter than B.
B: Four is incorrect as only E and C are shorter than B; C: One is incorrect because both E and C are shorter; D: Three is incorrect as there are only two people shorter than B.
A is correct because the height sequence is F > H > B > E > C, meaning only E and C are shorter than B.
In ranking puzzles, always define the direction (e.g., Tall to Short or Heavy to Light) first to avoid confusion when combining multiple conditional statements.
