In the writing challenge 'Melon with ham' we are asked to translate "You just need to cut some melon slices"

I wrote "Solo necesitas cortar algunas rodajas de melón" and it was corrected with "unas rodajas".

I understood these were interchangeable, and I'm yet to find any definitive to the contrary. Could someone please explain my error here?

Estoy un poco confundido. La celebración es la Fiesta de Quince Años y el celebrante es el Quinceañero/a, verdad?

Hi,

I came across the below question in the quiz on this lesson. Am I missing the part where “and she is affected by it” becomes important?

QUESTION: 

Choose the correct sentence expressing: "Her baby doesn't eat any fruit and she is affected by it."

CORRECT ANSWER: 

Su bebé no le come nada de fruta.

Other choices: 

You make the distinction that todavía can be placed before or after the verb unlike in English, but I think it can be done in English as well. It might be a bit less common (or perhaps more poetic), but I can think of sentences where it could come after the verb still. 

One of the lessons included things that were happening in the past but are still ongoing. Instead of the present perfect, it included the present tense and then something else (it was not this lesson). Could you tell me where that lesson is or explain it to me? Thanks.

I'm still confused by the use of "ser" and "estar" for different ideas related to location.  Is this pair of sentences correct?

El entierro es en el cementerio de su pueblo.  El cementerio está fuera del pueblo.
