update earth silver benchmark

[Zhouzone]

Motivation

This PR introduces a new benchmark dataset for Earth science-related multiple-choice questions (MCQ), named Earth_Silver_MCQ. The goal of this PR is to expand the benchmark suite with a dataset that targets Earth science topics, which can be used for evaluating models on domain-specific MCQ tasks.

Modification

• Added the Earth_Silver_MCQ benchmark dataset to the project.
• This dataset focuses on Earth science-related multiple-choice questions (MCQ) to help evaluate models' performance on domain-specific tasks.
• Pre-commit checks (like flake8, isort, yapf, etc.) have been applied to ensure code quality.

BC-breaking (Optional)

This modification does not introduce any backward compatibility-breaking changes to the project or other related repositories.

Use cases (Optional)

This new dataset can be used to evaluate models' performance on Earth science MCQs, making it easier to test how well models handle questions related to Earth science and related fields.
