When packing the order yesterday, one important item was omitted.
1. properly constructed sentence
2. comma splice
3. misplaced
4. lacks parallel parts
5. dangler

1.

it isn't a comma splice as the first part is not its own sentence.

the comma is in the correct place.

c.to compare several aspects of the tragedy to other worldwide tragedies
