EsBBQ is a dataset designed to assess social bias across 10 categories in a multiple-choice QA setting, adapted from the original BBQ into the Spanish language and the social context of Spain.
It is fully parallel with the `cabbq` task group, the version in Catalan.

### Groups and Tasks
#### Groups
*`esbbq`: Contains the subtasks that covers all demographic categories.
*`esbbq_{category}`: Subtask that evaluates on the given category's subset.
### Metrics
EsBBQ is evaluated with the following 4 metrics, at the level of each subtask and with aggregated values for the entire group:
*`acc_ambig`: Accuracy over ambiguous instances.
*`acc_disambig`: Accuracy over disambiguated instances.
*`bias_score_ambig`: Bias score over ambiguous instances.
*`bias_score_disambig`: Bias score over disambiguated instances.
See the paper for a thorough explanation and the formulas of these metrics.
### Checklist
For adding novel benchmarks/datasets to the library:
* [ ] Is the task an existing benchmark in the literature?
* [ ] Have you referenced the original paper that introduced the task?
* [ ] If yes, does the original paper provide a reference implementation? If so, have you checked against the reference implementation and documented how to run such a test?
If other tasks on this dataset are already supported:
* [x] Is the "Main" variant of this task clearly denoted?
* [x] Have you provided a short sentence in a README on what each new variant adds / evaluates?
* [x] Have you noted which, if any, published evaluation setups are matched by this variant?

Given an instance doc and the results from the evaluation, this function processes these results to transform them into the information that is necessary for the evaluation metrics to be calculated. Therefore, the returned dict contains information at an instance-level that will be required to calculate the final aggregated metrics over multiple instances (per category or for the entire dataset).
NOTE that the return value is not directly the result of the metric; there is no instance-level "bias score". The value of `bias_score_ambig` is the information necessary for `bias_score_ambig_agg` to aggregate and calculate bias score over ambiguous instances, for example.
Args:
doc (dict): The instance doc.
results (list): List with one tuple of results per multiple-choice option (thus 11 elements) where the first element is the loglikelihood of the option, and the second element is a boolean value of whether the corresponding option is correct or not (to be ignored because we don't use it).
Returns:
dict: Dictionary with tuples of values that shall be used to calculate each aggregated metric.
