In Spanish "my head hurts" is "me duele mi cabeza"
I'm not sure what you are talking about exactly, but I would think thats false.
Answer:
The correct answer is: su/sus
Explanation:
In Spanish, we can use the following structure to express the possession of a certain thing: <u>object + de + person</u>.
e.g. el libro de Juan
We also can replace the name of the person (3rd person of the singular) with a possessive adjective (su or sus).
e.g. su libro
We use the possessive adjectives to express who possesses something.
For plural forms, we use possessive adjective form - sus.
e.g. los libros de Juan y Ana = sus libros
I'm not sure of the vocab you're supposed to use, but I think it's: Manuel Carmen, estoy (I am) muy contento por ellos, pero eso (that) es algo enfermo y no puedo ir.
Hope that helps and is somewhat correct!
