Why
did the chinese attempt at reform fail

Hundred Days' Reform. The Hundred Days' Reform was a failed 103-day national, cultural, political, and educational reform movement from 11 June to 22 September 1898 in late Qing dynasty China. It was undertaken by the young Guangxu Emperor and his reform-minded supporters.

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.

nations must cooperate to bring about and maintain world peace.

nations must not wage wars or commit war crimes in a desire to control other nations.
