Problem: Please answer a question about the following article about Capacitor:
The current I(t) through any component in an electric circuit is defined as the rate of flow of a charge Q(t) passing through it, but actual chargeselectronscannot pass through the dielectric layer of a capacitor. Rather, one electron accumulates on the negative plate for each one that leaves the positive plate, resulting in an electron depletion and consequent positive charge on one electrode that is equal and opposite to the accumulated negative charge on the other. Thus the charge on the electrodes is equal to the integral of the current as well as proportional to the voltage, as discussed above. As with any antiderivative, a constant of integration is added to represent the initial voltage V(t0). This is the integral form of the capacitor equation:
What is the definition of the current I(t) through any component in an electric circuit?
A: the rate of flow of a charge Q(t) passing through it

One-third of Myanmar's total perimeter of 1,930 km (1,200 miles) forms an uninterrupted coastline along the Bay of Bengal and the Andaman Sea. The country's 2014 census revealed a much lower population than expected, with 51 million people recorded. Myanmar is 676,578 square kilometres (261,227 sq mi) in size. Its capital city is Naypyidaw and its largest city is Yangon (Rangoon).
What is the land mass of Myanmar ?
A: Myanmar is 676,578 square kilometres (261,227 sq mi) in size

Chengdu Economic and Technological Development Zone (Chinese: ; pinyin: Chengdu jingji jishu kaifa qu) was approved as state-level development zone in February 2000. The zone now has a developed area of 10.25 km2 (3.96 sq mi) and has a planned area of 26 km2 (10 sq mi). Chengdu Economic and Technological Development Zone (CETDZ) lies 13.6 km (8.5 mi) east of Chengdu, the capital city of Sichuan Province and the hub of transportation and communication in southwest China. The zone has attracted investors and developers from more than 20 countries to carry out their projects there. Industries encouraged in the zone include mechanical, electronic, new building materials, medicine and food processing.
How many countries are represented by the investors and developers of the CETDZ?
A:
20
