instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
Suppose there are 2 more newborns, then which number will be increased, 65%, 15.1% or 19.9%?, Context: As of 2000[update], children and teenagers (0–19 years old) make up 15.1% of the population, while adults (20–64 years old) make up 65% and seniors (over 64 years old) make up 19.9%.
answer:
15.1%


question:
What kind of dogs usually have docked tails?, Context: There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries. In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
answer:
hunting


question:
Which of the following does NOT raise efficiency: Stoke Shift loss, better package design, or a more suitable type of phosphor?, Context: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
answer:

Stoke shift loss
