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.

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.

Connie plants four plants A, B, C, and D in that order ( assuming it means chronologically and not planted in that order )
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

S1
We have rate comparison for A,B and C with no info on rate of D
Even, their planting time is unknown
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.

(1) Plant A grows at twice the rate of plant B and at half the rate of plant C.
A=2B and A=(1/2)C.... No comparison with D 
Insufficient

(2) Plant D averages 3.5 inches of growth per week.
D= 3.5 inches ....Nothing about A,B,C 
Insufficient

(1)&(2) together 
We don't know the relationship between D and any other plant. And also we don't know the rate at which A,B,C grows, so it's impossible to know which plant will reach 3.75 feet first. 
Insufficient
