Exams not accepting answers

This is the second question on this part 2 exam that is giving me an issue. I don’t know if it’s because (like a lot of the class work) it wants it to be done a specific way despite having multiple ways to answer - or if it’s a bug in the test itself (which I saw happen on another post).

I keep running out of checks for answers marked wrong and I don’t understand why.

Requirement: * All items in the #right container are right-justified with no extra spaces.
Answer:
#left {
justify-content: flex-start; /* Left-justify items */
}

I’m sorry, but we cannot help with exam questions as it’s against policy.
