Answer: 
G. 0.3 
Step-by-step explanation: 
We know that 
On April 1: Berry weight = 0.922 grams 
On April 12: Berry weight = 0.589 grams 
Therefore, the difference in weight is 
0.922 grams - 0.589 grams = 0.333 grams 
This means that the difference between the weight of the berry on April 1 and April 12 is 0.333 grams. 
Now which answer choice is closest to 0.333 grams? 
The answer is, choice G is the closest choice. 
Hence, choice G, 0.3 grams is the correct answer.
