The Sentence — Important Questions

It must make complete sense.

Step 1: According to the chapter, there are no fixed rules about the number of words in a sentence. So option A is wrong. Step 2: A sentence may not always begin with a noun — it can begin with other words too. So option B is not the most basic rule. Step 3: A sentence can end with a full stop, question mark, or exclamation mark, so option D is not the only rule. Step 4: The ONE basic feature of a sentence is that it MUST make complete sense. Step 5: Even a one-word sentence like 'Run.' makes complete sense, which confirms that complete sense is the most important feature.

Verb

Step 1: The chapter explains that even a one-word sentence is possible — examples given are 'Stand.', 'Run.', and 'Stop.' Step 2: All three one-word sentences are verbs (action words). Step 3: The chapter clearly states that 'the verb is the heart of a sentence.' Step 4: A noun names a person, place, or thing, but it alone cannot form a sentence. Adjectives and adverbs describe things, but they are not the heart of a sentence. Step 5: It is not possible to write a sentence without a verb, which is why the verb is called the heart of a sentence.

Step 1: A sentence must have words in the proper order and must make complete sense. Step 2: 'Stop.' is a one-word sentence that makes complete sense — it is a command. Step 3: 'The birds are singing.' has words in the correct order and makes complete sense — it is a sentence. Step 4: 'Are you coming?' asks a question with words in the proper order — it is a sentence. Step 5: 'running fast the boy' has words in a jumbled order and does not make complete sense — it is not a sentence.

Exclamatory

Step 1: Read the sentence — 'How beautiful the sunset is!' Step 2: Notice the word 'How' at the beginning and the exclamation mark (!) at the end — these are key clues. Step 3: The sentence is not stating a plain fact, asking a question, or giving a command. Step 4: It is expressing a strong feeling of admiration or wonder about the sunset. Step 5: A sentence that expresses a strong feeling is called an exclamatory sentence, and it ends with an exclamation mark (!). So this is an exclamatory sentence.
