Input: Read this: In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard. This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial. Only browsers that supported HTML5 Video using the H.264 or WebM formats could play the videos, and not all videos on the site were available.
Question: What format besides H.264 was playable with HTML5?

Output: WebM

Input: Read this: In previous times, at the consistory at which the pope named a new cardinal, he would bestow upon him a distinctive wide-brimmed hat called a galero. This custom was discontinued in 1969 and the investiture now takes place with the scarlet biretta. In ecclesiastical heraldry, however, the scarlet galero is still displayed on the cardinal's coat of arms. Cardinals had the right to display the galero in their cathedral, and when a cardinal died, it would be suspended from the ceiling above his tomb. Some cardinals will still have a galero made, even though it is not officially part of their apparel.[citation needed]
Question: What does the pope now wear when naming a new Cardinal?

Output: scarlet biretta

Input: Read this: The abbey became the coronation site of Norman kings. None were buried there until Henry III, intensely devoted to the cult of the Confessor, rebuilt the abbey in Anglo-French Gothic style as a shrine to venerate King Edward the Confessor and as a suitably regal setting for Henry's own tomb, under the highest Gothic nave in England. The Confessor's shrine subsequently played a great part in his canonisation. The work continued between 1245 and 1517 and was largely finished by the architect Henry Yevele in the reign of Richard II. Henry III also commissioned unique Cosmati pavement in front of the High Altar (the pavement has recently undergone a major cleaning and conservation programme and was re-dedicated by the Dean at a service on 21 May 2010).
Question: What architect continued work on the abbey?

Output: Henry Yevele

Input: Read this: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
Question: What is next to the continental shelves?
