Problem: Please answer a question about the following article about Solar energy:
Deciduous trees and plants have been promoted as a means of controlling solar heating and cooling. When planted on the southern side of a building in the northern hemisphere or the northern side in the southern hemisphere, their leaves provide shade during the summer, while the bare limbs allow light to pass during the winter. Since bare, leafless trees shade 1/3 to 1/2 of incident solar radiation, there is a balance between the benefits of summer shading and the corresponding loss of winter heating. In climates with significant heating loads, deciduous trees should not be planted on the Equator facing side of a building because they will interfere with winter solar availability. They can, however, be used on the east and west sides to provide a degree of summer shading without appreciably affecting winter solar gain.
The placement of deciduous trees on the Equator facing side of a building can have a negative effect on solar availability in which season?
A: winter

Problem: Please answer a question about the following article about Tibet:
For several decades, peace reigned in Tibet, but in 1792 the Qing Qianlong Emperor sent a large Chinese army into Tibet to push the invading Nepalese out. This prompted yet another Qing reorganization of the Tibetan government, this time through a written plan called the "Twenty-Nine Regulations for Better Government in Tibet". Qing military garrisons staffed with Qing troops were now also established near the Nepalese border. Tibet was dominated by the Manchus in various stages in the 18th century, and the years immediately following the 1792 regulations were the peak of the Qing imperial commissioners' authority; but there was no attempt to make Tibet a Chinese province.
When was Tibet dominated by the Manchus?
A: 18th century
Problem: Please answer a question about the following article about Marvel Comics:
Lee and freelance artist and eventual co-plotter Jack Kirby's Fantastic Four originated in a Cold War culture that led their creators to revise the superhero conventions of previous eras to better reflect the psychological spirit of their age. Eschewing such comic-book tropes as secret identities and even costumes at first, having a monster as one of the heroes, and having its characters bicker and complain in what was later called a "superheroes in the real world" approach, the series represented a change that proved to be a great success.
The emphasis on relatable settings and character motivations in Marvel's 1960s comics is called what?
A:
"superheroes in the real world"
