Here is a question about this article: In the 10th century the establishment of churches and monasteries led to the development of stone architecture that elaborated vernacular Roman forms, from which the term "Romanesque" is derived. Where available, Roman brick and stone buildings were recycled for their materials. From the tentative beginnings known as the First Romanesque, the style flourished and spread across Europe in a remarkably homogeneous form. Just before 1000 there was a great wave of building stone churches all over Europe. Romanesque buildings have massive stone walls, openings topped by semi-circular arches, small windows, and, particularly in France, arched stone vaults. The large portal with coloured sculpture in high relief became a central feature of facades, especially in France, and the capitals of columns were often carved with narrative scenes of imaginative monsters and animals. According to art historian C. R. Dodwell, "virtually all the churches in the West were decorated with wall-paintings", of which few survive. Simultaneous with the development in church architecture, the distinctive European form of the castle was developed, and became crucial to politics and warfare.

Here is a question about this article: The Samoan islands have been produced by vulcanism, the source of which is the Samoa hotspot which is probably the result of a mantle plume. While all of the islands have volcanic origins, only Savai'i, the western most island in Samoa, is volcanically active with the most recent eruptions in Mt Matavanu (19051911), Mata o le Afi (1902) and Mauga Afi (1725). The highest point in Samoa is Mt Silisili, at 1858 m (6,096 ft). The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km (20 sq mi) of solidified lava.
What is the answer to this question: What natural process formed the land masses that would become the Samoan islands?

So... vulcanism

Here is a question about this article: In August 2007, an increase in the price of diesel and petrol led to Saffron Revolution led by Buddhist monks that were dealt with harshly by the government. The government cracked down on them on 26 September 2007. The crackdown was harsh, with reports of barricades at the Shwedagon Pagoda and monks killed. There were also rumours of disagreement within the Burmese armed forces, but none was confirmed. The military crackdown against unarmed protesters was widely condemned as part of the International reactions to the Saffron Revolution and led to an increase in economic sanctions against the Burmese Government.
What is the answer to this question: What was the cause of the insurrection in the summer of 2007 ?
