¿En este ejemplo por qué la forma segunda persona singular del verbo dar se usa para el imperativo?

Here is my question in English, in case my question in Spanish is incorrect or just too awkward:

In this example, why is the 2nd person singular form of the verb, dar, used for the imperative?

Hi,

Hope all are well and keeping well. 

I was wondering if you could help me to know how to determine when to write “qu” or “c”. 

Also, one of the hints included the word “spa” which had nothing to do with the text, and there wasn’t any mention of spa in that section (or anywhere else).  

Thank you for your attention.

"It can be used in the singular, for example se tarda, se tardó or in the plural, for example se tardan, se tardaron. Se tardó dos horas en llegar. = Se tardaron dos horas en llegar. It took two hours to arrive."

So both examples mean precisely the same thing? Is there a situation where the meaning would change?

In the sentence:Ellas a luz a unos gemelos preciosos. (They gave birth to beautiful twins),

1) does "ellas" indicate 'several women gave birth to several sets of twins'? 

2) If a married couple had A set of twins, would that be ' ellOs a luz a un gemelo precioso?, Or does 'a luz' literally only refer to the mother who gives birth?

Thanks
