This question was previously asked in
CDS I 2017 General Knowledge Previous Year Paper (05-Feb-2017)
The correct answer is

Does not exist

Understanding Verb Usage: 'Exist' and Continuous Tenses

The original sentence is "This telephone number is not existing." We need to look at the underlined part, "is not existing," and determine if one of the given substitutions improves the sentence.

Let's analyze the original phrase and the options provided to find the best way to express that a telephone number does not exist.

Analyzing the Original Sentence: "is not existing"

The phrase "is not existing" uses the present continuous tense (is + verb-ing). The verb "exist" is generally considered a stative verb (or state verb). Stative verbs describe a state or condition rather than an action. Common examples include verbs related to:

  • Feelings: love, hate, want, need
  • Possession: have, own, possess
  • States of being/qualities: be, exist, seem, appear
  • Mental states: know, believe, understand, remember
  • Senses (often stative): see, hear, smell, taste, feel

Stative verbs are typically not used in continuous tenses (like present continuous) because they don't describe ongoing actions. Instead, they usually use simple tenses (like simple present or simple past) even when referring to a present state.

Therefore, using "is not existing" is grammatically incorrect and unnatural in standard English because 'exist' is a stative verb.

Evaluating the Substitution Options

Option (a): "Does not exist"

This option uses the simple present tense form "does not exist". The simple present tense is correctly used for stative verbs to describe a current state or fact. Saying "This telephone number does not exist" clearly and grammatically conveys that the telephone number is not in existence. This is the standard and correct way to express this idea.

Option (b): "Has not been existing"

This option uses the present perfect continuous tense (has/have + been + verb-ing). The present perfect continuous is used for actions that started in the past and continue up to the present, or for actions that have recently stopped but have a result in the present. Like the present continuous, it is generally not used with stative verbs. Using this tense with 'exist' is grammatically incorrect and makes the sentence sound awkward and unnatural.

Option (c): "Has had no existence"

This option uses the present perfect tense ("Has had") combined with the noun form "existence". While grammatically structured, "has had no existence" is an overly formal and less common way to express non-existence, especially for something straightforward like a telephone number. "Does not exist" is far more common, direct, and natural for this context.

Option (d): "No improvement"

As discussed, the original phrase "is not existing" is grammatically incorrect because 'exist' is a stative verb. Therefore, an improvement is needed.

Conclusion

Comparing the options, "Does not exist" is the only grammatically correct and natural-sounding substitution. It uses the simple present tense appropriately with the stative verb 'exist'.

Option Phrase Analysis Validity for 'Exist'
Original is not existing Present Continuous Incorrect for stative verb 'exist'
(a) Does not exist Simple Present Correct for stative verb 'exist'
(b) Has not been existing Present Perfect Continuous Incorrect for stative verb 'exist'
(c) Has had no existence Present Perfect + Noun Grammatically possible but unnatural/overly formal

Revision Table: Understanding Verbs and Tenses

Verb Type Description Typical Tenses Example (Exist)
Action Verbs Describe actions or processes (e.g., run, eat, write). Can typically be used in continuous tenses. Simple and Continuous Tenses (e.g., walk, is walking, walked, was walking) (Not 'exist' - this is a state verb)
Stative Verbs Describe states, conditions, or feelings (e.g., know, believe, love, exist). Generally not used in continuous tenses. Simple Tenses (e.g., know, knew, exists, existed) Exist, exists, existed (Correct)
Is existing, was existing (Incorrect/Rare exceptions)

Additional Information: Stative Verbs and Exceptions

While the general rule is that stative verbs are not used in continuous tenses, there are some exceptions, especially when a verb can have both a stative and an action meaning. For example:

  • "Have": Stative when meaning possession ("I have a car"). Action when meaning experience ("I am having dinner").
  • "Be": Stative when describing a quality ("He is tall"). Action when describing behavior ("He is being noisy" - implying temporary behavior).

However, the verb "exist" almost always refers to a state of being, which is why the simple present tense ("does not exist") is the correct form for expressing non-existence in the present.

Understanding the difference between stative and action verbs is crucial for using English tenses correctly, especially when dealing with continuous forms like the present continuous ("is existing").
