Problem: Please answer a question about the following article about Sahara:
The South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm (3.9 to 7.9 in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 km2 (425,400 mi2) in Algeria, Chad, Mali, Mauritania, and Sudan.
What is the average rainfall between the months of July and   August?
A: 100 to 200 mm
Problem: Please answer a question about the following article about Crucifixion of Jesus:
Another issue has been the use of a hypopodium as a standing platform to support the feet, given that the hands may not have been able to support the weight. In the 17th century Rasmus Bartholin considered a number of analytical scenarios of that topic. In the 20th century, forensic pathologist Frederick Zugibe performed a number of crucifixion experiments by using ropes to hang human subjects at various angles and hand positions. His experiments support an angled suspension, and a two-beamed cross, and perhaps some form of foot support, given that in an Aufbinden form of suspension from a straight stake (as used by the Nazis in the Dachau concentration camp during World War II), death comes rather quickly.
Why was a platform used?
A: the hands may not have been able to support the weight
Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:

 Thailand: The April 18 relay through Bangkok was the Olympic flame's first visit to Thailand. The relay covered just over 10 km, and included Bangkok's Chinatown. The torch was carried past Democracy Monument, Chitralada Palace and a number of other city landmarks. M.R. Narisa Chakrabongse, Green World Foundation (GWF) chairwoman, withdrew from the torch-running ceremony, protesting against China's actions in Tibet. Several hundred protesters were present, along with Olympic supporters. Thai authorities threatened to arrest foreign protesters and ban them from future entry into Thailand. A coalition of Thai human rights groups announced that it would organise a "small demonstration" during the relay, and several hundred people did indeed take part in protests, facing Beijing supporters. Intended torchbearer Mom Rajawongse Narissara Chakrabongse boycotted the relay, to protest against China's actions in Tibet. In Bangkok, students told the media that the Chinese Embassy provided them with transportation and gave them shirts to wear.
Who were told they would be banned from reentering Thailand?
A:
foreign protesters
