An ecommerce company wants to determine customer sentiment from written product reviews. Which AWS services can be used to meet this requirement? (Choose two.)

Amazon Comprehend is a natural language processing (NLP) service that uses machine learning to find insights and relationships in text. It can directly perform sentiment analysis on product reviews, making it a correct choice. Amazon Bedrock is a fully managed service that offers access to foundation models (FMs) from Amazon and third-party model providers via an API. These FMs can be used for various NLP tasks, including sentiment analysis, by leveraging or fine-tuning models like those from AI21 Labs, Anthropic, Cohere, Meta, or Stability AI. Amazon Lex is for building conversational interfaces (chatbots). Amazon Polly turns text into lifelike speech. Amazon Rekognition analyzes images and videos. These services do not directly perform text-based sentiment analysis.
