Dataset Card for ARC (Spanish Version)

Dataset summary

This dataset provides the Spanish translation and adaptation of the ARC (AI2 Reasoning Challenge) validation set. The original dataset was designed to evaluate scientific reasoning in LLMs by presenting a collection of authentic, grade-school science multiple choice questions split into two sets of varying difficulty: ARC Easy and ARC Challenging. This Spanish adaptation enables evaluation of the ARC task in Spanish while preserving the original Easy and Challenge splits and maintaining the conceptual difficulty, structure, and intent of the source material.

Dataset Details

Dataset Description

The dataset preserves the original structure, features, and overall format of the original ARC validation set. Only minor adjustments were made during translation. Key adaptations include:

1. Ensuring factual correctness, as some factual mistakes were found in the original
2. Preserving linguistic and cultural appropriateness in Spanish-speaking contexts
3. Adapting proper names to Spanish equivalents
4. Maintaning gender neutrality in items where the English source did not mark gender, in order to avoid introducing gender bias

Dataset Structure

ARC_Easy_es

An example of instance looks as follows:

{
  "id": "NYSEDREGENTS_2014_8_3",
  "question": "¿Qué tipo de relación hay cuando las raíces de un tipo determinado de árbol necesitan la presencia de un hongo para crecer con normalidad?",
  "answer_a": "Beneficiosa.",
  "answer_b": "Competitiva.",
  "answer_c": "Nociva.",
  "answer_d": "Infecciosa.",
  "answerkey": "A"}

ARC_Challenge_es

An example of instance looks as follows:

{
  "id": "Mercury_7235813",
  "question": "El carbono circula por diversos depósitos de la Tierra. El tiempo que tardan en formarse estos depósitos varía considerablemente. ¿Qué proceso del ciclo del carbono tarda millones de años en formar el depósito indicado?",
  "answer_a": "La incorporación del carbono a través de la digestión en los tejidos animales.",
  "answer_b": "La liberación de carbono en la atmósfera al respirar.",
  "answer_c": "El carbono atmosférico que se incorpora en los lípidos de las plantas.",
  "answer_d": "La descomposición del carbono en tejidos vegetales para generar petróleo.",
  "answerkey": "D"
}

Uses

Direct Use

This dataset can be used to:

• Evaluate scientific reasoning and multiple-choice question-answering in Spanish.
• Study multilingual performance variation in scientific question-answering.
• Assess model robustness on Easy and Challenge splits in a non-English context.

Out-of-Scope Use

This dataset is not intended for:

• Training or fine-tuning models, as it is intended strictly for evaluation.
• Drawing conclusions about real-world scientific expertise or student assessment.
• Generating outputs in scientific contexts without human oversight.
• Use in non-Spanish contexts, as the dataset has been culturally and linguistically localized.
