Final answer:
Gothic builders could open large areas for windows in their constructions by using pointed arches and flying buttresses, allowing for thinner walls and more light, symbolizing the divine.
Step-by-step explanation:
Gothic builders were able to open large areas for windows, because they used pointed arches and flying buttresses. The architectural innovations of the Gothic style, such as the use of flying buttresses and pointed arches, allowed for higher walls and larger windows in structures like cathedrals and churches.
This was not just an aesthetic choice but also a symbolic one, with the light through the windows representing the divine. With these supports, the builders could create walls that were thinner and filled with stained glass, which let in more light and created a sense of heaven on earth.
