	### Dataset Summary

	A new dataset of 7,787 genuine grade-school level, multiple-choice science questions, assembled to encourage research in
	advanced question-answering. The dataset is partitioned into a Challenge Set and an Easy Set, where the former contains
	only questions answered incorrectly by both a retrieval-based algorithm and a word co-occurrence algorithm. We are also
	including a corpus of over 14 million science sentences relevant to the task, and an implementation of three neural baseline models for this dataset. We pose ARC as a challenge to the community.

	## Dataset Structure

	### Data Instances

	#### ARC-Challenge

	- Size of downloaded dataset files: 680.84 MB
	- Size of the generated dataset: 0.83 MB
	- Total amount of disk used: 681.67 MB

	An example of 'train' looks as follows.
	```
	{
	"answerKey": "B",
	"choices": {
	"label": ["A", "B", "C", "D"],
	"text": ["Shady areas increased.", "Food sources increased.", "Oxygen levels increased.", "Available water increased."]
	},
	"id": "Mercury_SC_405487",
	"question": "One year, the oak trees in a park began producing more acorns than usual. The next year, the population of chipmunks in the park also increased. Which best explains why there were more chipmunks the next year?"
	}
	```

	#### ARC-Easy

	- Size of downloaded dataset files: 680.84 MB
	- Size of the generated dataset: 1.45 MB
	- Total amount of disk used: 682.29 MB

	An example of 'train' looks as follows.
	```
	{
	"answerKey": "B",
	"choices": {
	"label": ["A", "B", "C", "D"],
	"text": ["Shady areas increased.", "Food sources increased.", "Oxygen levels increased.", "Available water increased."]
	},
	"id": "Mercury_SC_405487",
	"question": "One year, the oak trees in a park began producing more acorns than usual. The next year, the population of chipmunks in the park also increased. Which best explains why there were more chipmunks the next year?"
	}
	```

	### Data Fields

	The data fields are the same among all splits.

	#### ARC-Challenge
	- `id`: a `string` feature.
	- `question`: a `string` feature.
	- `choices`: a dictionary feature containing:
	- `text`: a `string` feature.
	- `label`: a `string` feature.
	- `answerKey`: a `string` feature.

	#### ARC-Easy
	- `id`: a `string` feature.
	- `question`: a `string` feature.
	- `choices`: a dictionary feature containing:
	- `text`: a `string` feature.
	- `label`: a `string` feature.
