These are for the same location. I checked the address for the first one and it's the same as the second one. In Berkeley, all of the other LFLs are listed by address, so please keep the one listed second:
Little Free Library 14027 Little Free Library at 1521 Delaware St (keep this one)
These listings are for the same grocery store. I would keep the first one as the second one is slightly inaccurate (the store is technically located on Oregon Street, but Shattuck Avenue runs along one side of the parking lot):
The name of this restaurant is actually Brazil Cafe (not Brazilian Cafe). I would remove "on University Avenue" because it's redundant (there are actually two locations for this restaurant and they're both on University Avenue).
