 Four Sisters Crossed Birth Month Settlement (Posted on 2023-08-05)
Four sisters, Sandra, Olivia, Natalie, and Dakota, were each born in a different one of the following months: September, October, November, and December.

"This is terrible," said Olivia one day. "None of us have an initial that matches the initial of her birth month."

"I don't mind at all," replied the girl who was born in September.

"That's easy for you to say," said Natalie. "I would at least have been pleased if the initial of my birth month was a vowel, but no."

In which month was each girl born?

Dakota was born in September
Sandra was born in October
Olivia was born in November
Natalie was born in December

as

the September birthday was not Olivia.
Natalie was born in neither September nor October.

That leaves only the given order among orders that match no names with the corresponding months.
