Problem: The High Middle Ages was a period of great religious movements. Besides the Crusades and monastic reforms, people sought to participate in new forms of religious life. New monastic orders were founded, including the Carthusians and the Cistercians. The latter especially expanded rapidly in their early years under the guidance of Bernard of Clairvaux (d. 1153). These new orders were formed in response to the feeling of the laity that Benedictine monasticism no longer met the needs of the laymen, who along with those wishing to enter the religious life wanted a return to the simpler hermetical monasticism of early Christianity, or to live an Apostolic life. Religious pilgrimages were also encouraged. Old pilgrimage sites such as Rome, Jerusalem, and Compostela received increasing numbers of visitors, and new sites such as Monte Gargano and Bari rose to prominence.
When did Bernard of Clairvaux die?
The answer is the following: 1153

Problem: On 14 September 2009, U.S. Special Forces killed two men and wounded and captured two others near the Somali village of Baarawe. Witnesses claim that helicopters used for the operation launched from French-flagged warships, but that could not be confirmed. A Somali-based al-Qaida affiliated group, the Al-Shabaab, has confirmed the death of "sheik commander" Saleh Ali Saleh Nabhan along with an unspecified number of militants. Nabhan, a Kenyan, was wanted in connection with the 2002 Mombasa attacks.
Where was the Sep 14, 2009 action?
The answer is the following: near the Somali village of Baarawe

Problem: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
What is the effective f-number proportional to?
The answer is the following: the ratio between the lens focal length and aperture diameter

Problem: The USB Power Delivery revision 2.0 specification has been released as part of the USB 3.1 suite. It covers the Type-C cable and connector with four power/ground pairs and a separate configuration channel, which now hosts a DC coupled low-frequency BMC-coded data channel that reduces the possibilities for RF interference. Power Delivery protocols have been updated to facilitate Type-C features such as cable ID function, Alternate Mode negotiation, increased VBUS currents, and VCONN-powered accessories.
What does the USB Power Delivery revision 2.0 specification cover?
The answer is the following:
Type-C cable and connector with four power/ground pairs and a separate configuration channel
