It depends on which war you're referring to. I feel that the answer you're looking for is the radio, though.
For PLATO:
Maya: Created hieroglyphic writing system
Developed the accurate calendar systems
Constructed Chichen Itza
Aztec: Built Tenochtitlan
Sustained 20mil population
Grew floating gardens
1370 INR would be the answer to the first one because 54.80 times 25 =1370
24.75 is the answer to the second one because 25 times .99 = 24.75
South Africa is the answer to the third one
i think that you should write the paragraph but in South Africa 1$ is equal to over 8$ whereas in the EU 1$ equals only .75$
2013 it would have been cheaper to buy tablets from India <span />
Idk d it might be d i might be wrong
Return to normalcy would be the answer
