Problem: Gothic architecture:

Expansive interior light has been a feature of Gothic cathedrals since the first structure was opened. The metaphysics of light in the Middle Ages led to clerical belief in its divinity and the importance of its display in holy settings. Much of this belief was based on the writings of Pseudo-Dionysius, a sixth-century mystic whose book, The Celestial Hierarchy, was popular among monks in France. Pseudo-Dionysius held that all light, even light reflected from metals or streamed through windows, was divine. To promote such faith, the abbot in charge of the Saint-Denis church on the north edge of Paris, the Abbot Suger, encouraged architects remodeling the building to make the interior as bright as possible.

Whose writings led to the clerical belief in the divinity of light?

A: Pseudo-Dionysius

Problem: Portugal:

Similar to the other Eur-A countries, most Portuguese die from noncommunicable diseases. Mortality from cardiovascular diseases (CVD) is higher than in the eurozone, but its two main components, ischaemic heart disease and cerebrovascular disease, display inverse trends compared with the Eur-A, with cerebrovascular disease being the single biggest killer in Portugal (17%). Portuguese people die 12% less often from cancer than in the Eur-A, but mortality is not declining as rapidly as in the Eur-A. Cancer is more frequent among children as well as among women younger than 44 years. Although lung cancer (slowly increasing among women) and breast cancer (decreasing rapidly) are scarcer, cancer of the cervix and the prostate are more frequent. Portugal has the highest mortality rate for diabetes in the Eur-A, with a sharp increase since the 1980s.

What are the two main components of cardiovascular disease?
---
A: ischaemic heart disease and cerebrovascular disease
