How did american entry into world war i affect the allied powers?

What reason did yurovsky give nicholas ii for his pending execution? the czar’s relatives were about to rescue the romanovs. nicholas had committed crimes against the russians. nicholas had misused his power to abuse his own people. nicholas had not lived up to his duties as czar of russia. the answers are not b and c, i already tried those.
