Explanation

Amazon Textract + Amazon Bedrock (Titan Text or Claude) is the correct combination because:

• Amazon Textract is specifically designed to extract text and data from documents, including clinical-trial documents, PDFs, and scanned files
• Amazon Bedrock provides access to foundation models like Titan Text and Claude that are excellent for text summarization and extracting key insights from large documents
• This combination directly addresses the need to process clinical-trial documents and extract meaningful findings

Why other options are incorrect:

• B) Amazon Rekognition + Amazon Translate: Rekognition is for image/video analysis, not document processing
• C) Amazon Transcribe + Amazon S3: Transcribe is for speech-to-text, not document processing
• D) Amazon Polly + Amazon Comprehend: Polly is for text-to-speech, which doesn't help with document summarization

This solution enables automated document processing and intelligent summarization to accelerate pharmaceutical research workflows.
