Answer:
Nostalgia.
Step-by-step explanation:
The term "nostalgia" refers to the feeling of sentiment, missing, or yearning for something that's from the past. In other words, it is used to talk of things that one misses from previous times or days.
In the given passage, the word "missed" is used often to describe the Grandmother and how she felt. Though describing the many things that the Grandmother used to do and have, the main point of the passage is to show the yearning for those things. This is known as nostalgia, for the Grandmother 'missed' all those things that she used to have.
Thus, the correct answer is nostalgia.
