So, the question is about a wind turbine with two points, M and N, on the same blade. We need to determine which statement is correct regarding their motion. First, I remember that when objects are rotating about the same axis, like points on a wind turbine blade, the...	### Image 1: Physics / Mechanics Diagram Scene Summary: A black-and-white photograph of a wind turbine with two labeled points (M and N) on a single rotating blade, used to analyze rotational motion properties.

Linear velocity and centripetal acceleration increase with distance from the center, so if M is closer to the center than N, M has smaller linear velocity and smaller centripetal acceleration. Thus, statement C ...	true

MMFineReason-Full-2.3M

The Complete Pre-Selection Dataset — Before Quality Filtering

📖 Overview

MMFineReason-Full-2.3M is the complete pre-selection dataset containing 2.3M samples and 8.8B solution tokens, generated through our reasoning distillation pipeline before the data selection stage. This dataset includes all samples that passed basic template and length validation, but have not undergone correctness verification filtering.

🎯 Key Characteristics

2,286,130 Total Samples with 8.8B Solution Tokens
Pre-Selection Data: Contains both consistent and inconsistent samples
Research Purpose: Enables study of data quality, filtering strategies, and consistency patterns

⚠️ Important Note

This dataset is released for research purposes. For training, we recommend using the filtered MMFineReason-1.8M which removes ~20% inconsistent samples. This full version is valuable for:

Studying consistency patterns across different domains
Developing better filtering strategies
Analyzing the relationship between difficulty and consistency
Ablation studies on data quality

🔍 Consistency Analysis

We verify each sample by comparing the extracted answer from the <answer> tag against the ground truth.

High-Consistency Datasets: ScienceQA (96%), TQA (86%), MMR1 (85%) — well-posed samples with clear ground truths
Challenging Datasets: VisualSphinx (36%), Raven (39%), Geometry3K (54%) — abstract reasoning tasks with inherent difficulty or ambiguous samples
Overall: ~79% of samples are consistent (1.81M / 2.29M), forming the basis for MMFineReason-1.8M

📊 Dataset Statistics

Dataset Composition

Data Cleaning Statistics

Starting from 2,372,320 raw samples:

Length Filtering: Removed 1,806 samples exceeding context limits or anomalously short
Template Filtering: Removed 84,484 samples with parsing errors or malformed <think>/<answer> structure
Retention Rate: 96.36% (2,286,130 samples remain)

Most datasets show >95% retention. Slightly lower rates for VisualSphinx (93.1%) and Geometry3K (92.4%) due to complex formatting requirements.

Pass Rate and Consistency Statistics

Key Findings:

Strong positive correlation between Pass Rate and Consistency Rate
High-consistency datasets (ScienceQA, AI2D, TQA) have clear ground truths and high pass rates (>0.8)
Challenging tasks (Raven, VisualSphinx) show low pass rates (<0.25) and consistency (<40%)
