Answer:
The second one (Only 3 seeds will not sprout)
Explanation:
The first one is supported because it basically is adding a extra 0 at the end of each number and 210 is higher than 200
The second one is not supported because it is suppose to add a zero and there is none
The third one is not supported because with the added 0 is basically 240 - 30 = 210
The fourth one is supported because since the equation is 240 - 30 = 210, 210 is bigger than 30
