- an Elementary Science Question, such as: “What is the main purpose of the flowers of a peach tree?.
- See: Simple Question.

- QUOTE: Question Answering for complex questions is often modeled as a graph construction or traversal task, where a solver must build or traverse a graph of facts that answer and explain a given question. This "multi-hop" inference has been shown to be extremely challenging, with few models able to aggregate more than two facts before being overwhelmed by “semantic drift", or the tendency for long chains of facts to quickly drift off topic. This is a major barrier to current inference models, as even elementary science questions require an average of 4 to 6 facts to answer and explain. …
Q: What is the main purpose of the flowers of a peach tree?
A: to attract bees for pollination.Example Ratings:
High: The flower helps the plant reproduce because it contains the pollen and eggs.
