Final answer:
The holiest day of the Jewish year is Yom Kippur, while Passover is another major holiday that recounts the story of the Exodus. The site in Jerusalem significant to Christians is the Holy Sepulchre.
Step-by-step explanation:
The holiest day of the Jewish calendar year is Yom Kippur (b). In contrast, Passover is another significant Jewish holiday that commemorates the exodus of the Israelites from slavery in Egypt under the leadership of Moses. As the Book of Exodus describes, during Passover a child will ask, "Why is this night different from all other nights?", initiating the telling of the Passover story. Answering the other question, the site in Jerusalem of particular importance to Christians is the Holy Sepulchre (a).
