Multiple Choice

Which of the following statements is false?

• A) An xe "n-grams"n-gram is a sequence of n text items, such as letters in words or words in a sentence. In natural language processing, n-grams can be used to identify letters or words that frequently appear adjacent to one another.
• B) For text-based user input, n-grams can help predict the next letter or word a user will type-such as when completing items in IPython with tab-completion or when entering a message to a friend in your favorite smartphone messaging app. For speech-to-text, n-grams might be used to improve the quality of the transcription.
• C) You can pass the keyword argument n to TextBlob's ngrams method to produce n-grams of any desired length.

• In [2]: text = 'Today is a beautiful day. Tomorrow looks like bad weather.'
• In [3]: blob = TextBlob(text)
• In [4]: blob.ngrams()
• Out[4]:
• [WordList(['Today', 'is', 'a']),
• WordList(['is', 'a', 'beautiful']),
• WordList(['a', 'beautiful', 'day']),
• WordList(['beautiful', 'day', 'Tomorrow']),
• WordList(['day', 'Tomorrow', 'looks']),
• WordList(['Tomorrow', 'looks', 'like']),
