For most adjectives, the endings are like this:
o : masculine singular
os : masculine plural
a : feminine singular
as : feminine plural
La abuela means the grandmother. It is a feminine singular word. Therefore, you use the ending -a, so the answer is vieja.
Also, keep in mind that the adjective endings match noun endings. Abuela has the ending -a, so the adjective should also end in -a.
Panamanian sancocho originated in the Azuero region of the country, and Panamanians swear by eating a bowl of the hot soup for lunch on the hottest days, to help cool off. Sancocho is regarded almost as an elixir of life in Panama.
