In the quiz, I selected "Había muchos niños en el parque." This was marked wrong, rather, "Hubo muchos niños en el parque." 

I'm wondering why my answer was marked wrong, given that one of the examples in the lesson is nearly identical to my answer: "Había un perro en el parque."

I love reading and listening to the travel stories, or diaries.  These 3 audios are perfect examples. 
Even though we can google all the needed information, it´ll be even greater if some culture insights or backgrounds can be included in the introduction to these lessons, especially when talking about local cuisines.  

Question about ¡Qué delicioso! 
 in the text, the mochilero had eaten all the food in feminine forms, such as arroz, trucha frita, yuca y salsa. 
Shouldn't it be 
¡Qué deliciosa! instead?

I have a question about constructions like this: "Omar y Cristina son nuestros panaderos," e.g. "Omar and Cristina are our bakers." I understand it is "nuestros" because it is the nosotros form of the possessive adjective. However, I'm confused about the gender. Why is it masculine here?

¿Se quita la s del imperativo de nosotros cuando "selo" lo sigue?  Por ejemplo: mostremosselo o mostremoselo

In the kwiz, there was a phrase to complete: "Me vi tentada ..." I had selected tentado instead of tentada, which was marked wrong. The thing was that there was no indication, neither in the sentence itself or in the instructions, that the speaker was female. Why then would "Me vi tentado..." be incorrect?

What's the difference between "que" and "quien"

I don't understand why this is wrong:

"Los fontaneros, ________ vienen esta tarde, van a arreglar el grifo."

Why is it "que" insteda of "quien"?

Why a before bergamota?

For example "They are talking about the least successful novel ever written", can I say "Hablan de la novela menos exitosa jamás escrita"?
