Height Comparison Analysis
We need to determine the number of students shorter than student D based on the given height comparisons.
Establishing Height Relationships
Let's break down the given statements and represent them using inequalities:
- D is shorter than B: $D < B$
- D is taller than A: $D > A$ (or $A < D$)
- Combining the first two: $A < D < B$
- B is shorter than C: $B < C$. This extends the chain: $A < D < B < C$
- A is taller than E: $A > E$ (or $E < A$)
- A is taller than F: $A > F$ (or $F < A$)
Identifying Students Shorter Than D
From the combined inequality $A < D < B < C$, we know that A is shorter than D.
We also know that both E and F are shorter than A ($E < A$ and $F < A$).
Since E and F are shorter than A, and A is shorter than D, it follows that E and F are also shorter than D.
Therefore, the students shorter than D are A, E, and F.
Counting the Students
Counting the students identified (A, E, F), we find there are 3 students shorter than D.
