Problem: Sichuan:

The Yangtze River and its tributaries flows through the mountains of western Sichuan and the Sichuan Basin; thus, the province is upstream of the great cities that stand along the Yangtze River further to the east, such as Chongqing, Wuhan, Nanjing and Shanghai. One of the major tributaries of the Yangtze within the province is the Min River of central Sichuan, which joins the Yangtze at Yibin. Sichuan's 4 main rivers, as Sichuan means literally, are Jaling Jiang, Tuo Jiang, Yalong Jiang, and Jinsha Jiang.

Which tributary of the Yangtze flows through central Sichuan?
---
A: Min River


Problem: God:

Some findings in the fields of cosmology, evolutionary biology and neuroscience are interpreted by atheists (including Lawrence M. Krauss and Sam Harris) as evidence that God is an imaginary entity only, with no basis in reality. A single, omniscient God who is imagined to have created the universe and is particularly attentive to the lives of humans has been imagined, embellished and promulgated in a trans-generational manner. Richard Dawkins interprets various findings not only as a lack of evidence for the material existence of such a God but extensive evidence to the contrary.

How does Dawkins interpret evidence for or against the existence of God?
---
A: a lack of evidence for the material existence


Problem: Aircraft carrier:

In August 2013, a launching ceremony for Japan's largest military ship since World War II was held in Yokohama. The 820-foot-long (250 m), 19,500-ton flattop Izumo was deployed in March 2015. The ship is able to carry up to 14 helicopters; however, only seven ASW helicopters and two SAR helicopters were planned for the initial aircraft complement. For other operations, 400 troops and fifty 3.5 t trucks (or equivalent equipment) can also be carried. The flight deck has five helicopter landing spots that allow simultaneous landings or take-offs. The ship is equipped with two Phalanx CIWS and two SeaRAM for its defense. The destroyers of this class were initially intended to replace the two ships of the Shirane class, which were originally scheduled to begin decommissioning in FY2014.

How many troops can Japan's largest military ship carry?
---
A: 400


Problem: Antenna (radio):

The polarization of an antenna refers to the orientation of the electric field (E-plane) of the radio wave with respect to the Earth's surface and is determined by the physical structure of the antenna and by its orientation; note that this designation is totally distinct from the antenna's directionality. Thus, a simple straight wire antenna will have one polarization when mounted vertically, and a different polarization when mounted horizontally. As a transverse wave, the magnetic field of a radio wave is at right angles to that of the electric field, but by convention, talk of an antenna's "polarization" is understood to refer to the direction of the electric field.

When is a magnetic fields right angles to a electrical field?
---
A:
transverse wave
