Answer:
We must complete the sentence:
"Durante las Navidades y las Pascuas muchas personas van a la iglesia para la ________."
Where a rough translation of this is:
During Christmas and Easter many people go to church for ________.
Here the word that completes the sentense is "misa" or "mass" in english.
Actually, the one celebrated in the 25 is called "misa del gallo" or "misa de la aurora".
The complete sentence is:
"Durante las Navidades y las Pascuas muchas personas van a la iglesia para la misa"
