Let’s determine which plant (A, B, C, D) reaches 3.75 feet tall first.
Four plants start at 0, grow at constant rates. We compare times to 3.75 feet.
Neither statement alone nor together compares all rates to find the first to 3.75 feet.
Answer: E
Four plants start at 0, grow at constant rates. We compare times to 3.75 feet.
| Source | Information | Sufficiency |
| Stem | Plants A, B, C, D start at 0; constant rates | Insufficient, no rates |
| Statement 1 | A: 2x B rate, 0.5x C rate | Insufficient, no D rate |
| Statement 2 | D: 3.5 inches/week | Insufficient, no A, B, C rates |
| Statements 1 + 2 | A, B, C rates related; D: 3.5 inches/week | Insufficient, no D vs. A, B, C link |
Neither statement alone nor together compares all rates to find the first to 3.75 feet.
Answer: E

All the plants grow at constant rates
Which plant will be the first one to reach 3.75 feet tall?
Given this, we need the time when each of these were planted and their individual rates

Insufficient
S2
We have rate for D with no info on rate of A,B and C
Even, their planting time is unknown
Insufficient
Together, we do not have actual rates of A,B and C and their planting time. Insufficient.
