Find the part of the given sentence that has an error in it. If there is no error, choose ‘No error’.

Biodiversity has not evenly distributed, rather / it varies greatly across the globe as / well as within regions. / No Error

Correct option is A

The error is in part (A): “Biodiversity has not evenly distributed, rather …”

• What is wrong in (A)?

·       The sentence intends to say that biodiversity is not distributed evenly. Here, “distributed” is an action done to biodiversity (not done by biodiversity). So, the sentence needs a passive verb structure.

·       But the given phrase uses “has not + distributed” without “been”, which makes the verb structure incomplete.

·       In present perfect tense, we cannot directly write: has + V³ for passive meaning. We must add been.

• Correct sentence (fixed):

·       Biodiversity has not been evenly distributed; rather, it varies greatly across the globe as well as within regions.

• Why “rather” is used?

·       “Rather” introduces a contrast/correction: not evenly distributed; instead, it varies greatly.

·       Punctuation wise, semicolon (;) or full stop works better than a comma before “rather” in formal writing, but the main grammatical error is the missing been.

• Why (B) and (C) are correct?

·       (B) “it varies greatly across the globe as” is correct because “varies” agrees with singular subject “it” (biodiversity).

·       (C) “well as within regions” correctly completes the pair as well as and shows addition: across the globe + within regions.

Grammar Rule (English)

• Present Perfect (Active): has/have + V³

·       Example: They have completed the work.

• Present Perfect Passive: has/have + been + V³

·       Example: The work has been completed.

• In this question:

·       Wrong: Biodiversity has not evenly distributed.

·       Correct: Biodiversity has not been evenly distributed.

Grammar Rule (Hindi)

• Present Perfect (Active) का ढाँचा: has/have + V³

·       उदाहरण: They have finished the task. (उन्होंने काम पूरा कर लिया है।)

• Present Perfect Passive का ढाँचा: has/have + been + V³

·       उदाहरण: The task has been finished. (काम पूरा कर दिया गया है।)

• इस वाक्य में “distributed” (वितरित) कर्मवाच्य (Passive) अर्थ दे रहा है, इसलिए been लगाना जरूरी है।

·       गलत: Biodiversity has not evenly distributed.

·       सही: Biodiversity has not been evenly distributed.

Thus, Option (A) contains the error because “been” is missing in the present perfect passive structure.
