**Exercise: Context-Free Grammar (CFG) for Natural Language****Objective:**Define a Context-Free Grammar (CFG) for Natural Language to demonstrate that the following sentences would have very similar derivations and therefore can be well-formed: 1. A beautiful girl sings.2. A green idea dances.**Discussion:**The task requires defining the rules of a CFG that generate the given sentences. A well-formed CFG allows the decomposition of sentences into their grammatical components, ensuring that similar structures share derivational processes.**Example Sentences:**- A beautiful girl sings.- A green idea dances.**Steps to Define CFG:**1. Identify the components of the sentences: - Determiner (Det): "A" - Adjective (Adj): "beautiful", "green" - Noun (N): "girl", "idea" - Verb (V): "sings", "dances"2. Define the production rules: Here, S represents a sentence, NP denotes a noun phrase, and VP stands for a verb phrase. ``` S → NP VP NP → Det Adj N VP → V Det → 'A' Adj → 'beautiful' | 'green' N → 'girl' | 'idea' V → 'sings' | 'dances' ```**Explanation:**According to the production rules:- *S* (Sentence) is broken down into *NP* (Noun Phrase) and *VP* (Verb Phrase).- *NP* is further broken down into *Det* (Determiner), *Adj* (Adjective), and *N* (Noun).- *VP* for the given sentences only contains a *V* (Verb).- The terminals ('A', 'beautiful', 'green', 'girl', 'idea', 'sings', 'dances') are the actual words in the sentences.**Derivation for "A beautiful girl sings":**1.
