Problem: Geological history of Earth:

The Cambrian is a major division of the geologic timescale that begins about 541.0 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.

What continent ranged over the majority of the southern hemisphere of earth in the Cambrian?
---
A: Panthalassa

Problem: University:

Many scholars (including Makdisi) have argued that early medieval universities were influenced by the religious madrasahs in Al-Andalus, the Emirate of Sicily, and the Middle East (during the Crusades). Other scholars see this argument as overstated. Lowe and Yasuhara have recently drawn on the well-documented influences of scholarship from the Islamic world on the universities of Western Europe to call for a reconsideration of the development of higher education, turning away from a concern with local institutional structures to a broader consideration within a global context.

Who argues that many religious madrashas were influenced by medieval universities?
---
A: unanswerable

Problem: Intellectual property:

Some critics of intellectual property, such as those in the free culture movement, point at intellectual monopolies as harming health (in the case of pharmaceutical patents), preventing progress, and benefiting concentrated interests to the detriment of the masses, and argue that the public interest is harmed by ever-expansive monopolies in the form of copyright extensions, software patents, and business method patents. More recently scientists and engineers are expressing concern that patent thickets are undermining technological development even in high-tech fields like nanotechnology.

what concentrated intersts for tha benefit of the masses?

A:
unanswerable
