Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. When saying hallel with the minyan, are you supposed to say "hodu lashem ki tov ki l'olam chasdo" after the chazzan says the last line, even though that is the end of the little poem there and there is nothing else to say after the chazzan says that last line? Thanks.

Question
Birkat HaMazon has full and short versions similar to Hallel and Half Hallel. For Half Hallel, entire verses 115:1-11 and 116:1-11 are eliminated. However, for Birkat HaMazon short version, parts of verses are eliminated, not entire verses. Why did they eliminate partial verses (i.e., words within verses) rather than entire verses? How did they decide what to eliminate in Birkat HaMazon? It makes it very difficult to compare the full vs the short versions.

Question
Rabbi, I read that "Hallel should be recited during the day and not at night." Please explain why. Thanks.
