Here is a question about this article: Kerry "has emerged in the past few years as an important envoy for Afghanistan and Pakistan during times of crisis," a Washington Post report stated in May 2011, as Kerry undertook another trip to the two countries. The killing of Osama bin Laden "has generated perhaps the most important crossroads yet," the report continued, as the senator spoke at a press conference and prepared to fly from Kabul to Pakistan. Among matters discussed during the May visit to Pakistan, under the general rubric of "recalibrating" the bilateral relationship, Kerry sought and retrieved from the Pakistanis the tail-section of the U.S. helicopter which had had to be abandoned at Abbottabad during the bin Laden strike. In 2013, Kerry met with Pakistan's army chief Gen. Ashfaq Parvez Kayani to discuss the peace process with the Taliban in Afghanistan.
What is the answer to this question: Who was Pakistan's army chief in 2013?
****
So... Gen. Ashfaq Parvez Kayani

Here is a question about this article: As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently. Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the "Red Baron" is believed to have been shot down by an anti-aircraft Vickers machine gun. When the war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft weapons would be based around heavy weapons attacking high-altitude targets and lighter weapons for use when they came to lower altitudes.
What is the answer to this question: What made acquiring targets and aiming more required?
****
So...
increasing capabilities of aircraft
