"Definitions" are the generic name for top-level statements in the document.
Examples of this include:
1) Operations (such as a query)
2) Fragments
"Operations" are a generic name for requests in the document.
Examples of this include:
1) query,
2) mutation
"Selections" are the statements that can appear legally and at
single level of the query. These include:
1) field references e.g "a"
2) fragment "spreads" e.g. "...c"
3) inline fragment "spreads" e.g. "...on Type { a }"
