Alguém bom de inglês pode me ajudar com essa pergunta?

36. Read the extract below and answer the question that follows.
After years in the wilderness, the term ‘artificial intelligence’ (AI) seems poised to make comeback. AI was big in the 1980s but vanished in the 1990s. It re-entered public consciousness with the release of AI, but the term is also being used once more within the computer industry. Researchers, executives and marketing people are now using the expression without irony or inverted commas. And it is not always hype. The term is being applied with some justification, to products that depend on technology that was originally developed by AI researchers. Admittedly, the rehabilitation of the term has a long way to go, and some firms still prefer to avoid using it. But the fact that others are starting to use it again suggests that AI has moved on from being seen as an over-ambitious and under-achieving field of research.
Which statement is not mentioned in the text?

A) Researchers are more confident about using the term.
B) It will take some time to reestablish the term.
C) AI seems certain to come back.
D) Applications of AI have been successful.
E) AI has been obliterated for years.
