About each answer
A. Comprehend uses natural language processing to read text and return sentiment, key phrases and entities. It matches the reader comment need without a custom model.
B. Lex runs conversations with users in voice or text. None of the five jobs is a dialogue, so this is the option that is not used.
C. Polly converts written text into natural-sounding speech. It matches the need to read article summaries aloud in a listening app.
D. Textract reads scanned documents and returns their text, tables and form fields. It matches the need to pull data out of contracts and invoices.
E. Transcribe turns recorded speech into text, which suits the podcast archive. It matches the need to make the recordings searchable.
F. Translate converts text from one language into another. It matches the need to publish the same article in Spanish and German.
Explanation
Each AWS AI service handles one kind of input or output. Transcribe turns speech into text, Polly turns text into speech, Comprehend analyzes the meaning of text, Textract extracts data from documents, and Translate converts between languages. Lex builds dialogues, which none of the five jobs needs. This question tests matching each job to the service built for it.
