Understanding Verb Forms After 'Did Not'
The question asks us to find the most appropriate way to replace the underlined part of the sentence: "Kunal did not anticipate the need, so he did not carries his own water bottle."
Let's look closely at the underlined segment: "so he did not carries his own water bottle". The main verb phrase here is "did not carries".
Analyzing the Original Sentence Structure
The sentence uses the past tense auxiliary verb "did not". A fundamental rule of English grammar is that when you use the auxiliary verb "did" (in positive questions or negative statements with "did not"), the main verb that follows must be in its base form (also known as the infinitive form without "to").
- Incorrect form: did not + verb in past tense (e.g., did not carried)
- Incorrect form: did not + verb with -s/-es (e.g., did not carries/goes)
- Correct form: did not + base form of the verb (e.g., did not carry/go)
In the original sentence, "carries" is the third-person singular present tense form of the verb "carry". Following "did not", we need the base form, which is "carry". Therefore, "did not carries" is grammatically incorrect.
Evaluating the Options for Substitution
Now let's examine the provided options:
- so he does not carry his own: This option uses the present tense auxiliary "does not". The first part of the sentence, "Kunal did not anticipate the need," is in the past tense. Using "does not" in the second part creates a tense inconsistency. Also, while "carry" is the correct base form after "does not", the tense doesn't fit the overall sentence context.
- so he did not carry his own: This option uses the past tense auxiliary "did not" followed by the base form of the verb, "carry". This correctly follows the rule for using "did not" and maintains consistency with the past tense established in the first part of the sentence ("did not anticipate").
- so he did not carried his own: This option uses "did not" followed by the past tense form of the verb, "carried". As explained earlier, after "did not", the base form of the verb must be used, not the past tense form. So, this option is grammatically incorrect.
- No substitution required: The original segment "did not carries" is grammatically incorrect because it uses the -s form of the verb after "did not". Therefore, substitution is required.
Conclusion on the Correct Option
Based on the grammatical rule that the base form of the verb follows "did not", and considering the need for tense consistency within the sentence, the most appropriate substitution for "did not carries his own water bottle" is "did not carry his own water bottle".
This makes option 2 the correct choice.

Additional Information: Understanding Base Form
The base form of a verb is the simplest form, the one you typically see listed in a dictionary entry. It is the form without any endings like -s, -ed, or -ing.
- Verb: walk, Base form: walk
- Verb: eats, Base form: eat
- Verb: talked, Base form: talk
- Verb: swimming, Base form: swim
- Verb: carries, Base form: carry
Knowing the base form is crucial for using auxiliary verbs correctly in negative statements and questions, especially with "do," "does," and "did," and with modal verbs.
