Answer
The student chose the large power source because it provides a balance between the number of charges and the weight. It is more efficient as it provides more charges than the compact one and is lighter than the high capacity one.
Explanation
This question is asking for a suggestion as to why a student chose the "large" power source over the other options. The data provided in Table 1 shows that the "large" power source provides 5 charges and weighs 200 grams. This is compared to the "compact" power source, which provides only 1 charge and weighs 100 grams, and the "high capacity" power source, which provides 10 charges and weighs 600 grams. The student may have chosen the "large" power source because it provides a balance between the number of charges and the weight of the power source. The "compact" power source, while lighter, provides fewer charges, and the "high capacity" power source, while providing the most charges, is significantly heavier. Therefore, the "large" power source could be seen as the most efficient option, providing a good number of charges for its weight.
