On the Jewish holy day of __________, Egypt and Syria attacked Israel.A) Passover B) Chanukah C) Rosh Hashanah D) Yom Kippur
Although all of the days that you mention here are Jewish holy days, the only correct answer to this question is D. This attack happened in 1973. The war that followed the attack has come to be known as the Yom Kippur War.
The Arab attack on Israel was purposely timed to occur on Yom Kippur. Yom Kippur is seen as the holiest day of the Jewish year. Because of this, the Arabs believed that a surprise attack on that day would be likely to catch the Israelis unprepared. The initial attack nearly worked and Israel was nearly defeated. However, with US help, Israel rallied and defeated its attackers.
