Identify the segment in the sentence which contains an error. If there is no error, select 'No error'.

The sentence given below is divided into four segments labelled P, Q, R, and S. Read the sentence carefully to determine which segment contains a grammatical, syntactic, or idiomatic error. Select the letter corresponding to that specific segment as your answer. (Note: Every sentence contains exactly one error. Ignore errors of punctuation, if any.)

(P) Equipped with advanced bio-luminescent sensors,
(Q) the deep-sea submersible sounded cautious as it navigated
(R) the uncharted hydrothermal vents, monitoring for volatile acoustic signatures
(S) that could signal an imminent volcanic eruption.

Answer और ExplanationAnswer and explanation

Answer: (B) Q

Sounded एक linking verb है और उसके बाद adjective आता है, इसलिए sounded cautious केवल यह बताता है कि पनडुब्बी सुनने में कैसी प्रतीत होती है। यहाँ यह बताना है कि वह आगे बढ़ते समय किस ढंग से चली, इसलिए action verb के साथ adverb की आवश्यकता है।
✓
... the deep-sea submersible moved cautiously as it navigated ...
Segments P, R और S शुद्ध हैं।
सरल अर्थ: उन्नत संवेदकों से युक्त गहरे समुद्र की पनडुब्बी सावधानी से चलते हुए ज्वालामुखीय छिद्रों पर नज़र रख रही थी।
The verb sounded is a linking verb and takes an adjective, so sounded cautious only describes how the submersible seems to the listener. The sentence is about how it moved while navigating, which needs an action verb with an adverb.
✓
... the deep-sea submersible moved cautiously as it navigated ...
Segments P, R and S are correct.

बाकी Options उत्तर क्यों नहीं हैंWhy the other options are not the answer

A'P' अशुद्ध प्रतीत हुआ क्योंकि 'Equipped with' से वाक्य modifier की तरह आरंभ होता है। परंतु यह participle phrase (कृदंत पदबंध) कर्ता पनडुब्बी का सही वर्णन करता है।'P' seemed wrong because 'Equipped with' opens the sentence like a modifier. But the participle phrase correctly describes the submersible, which is the subject.
C'R' अशुद्ध प्रतीत हुआ क्योंकि 'monitoring for' कुछ अटपटा लगता है। परंतु 'monitor for' सामान्य प्रयोग है और यह phrase पनडुब्बी को सही modify करता है।'R' seemed wrong because 'monitoring for' feels unusual. But 'monitor for' is a normal pattern, and the phrase correctly modifies the submersible.
D'S' अशुद्ध प्रतीत हुआ क्योंकि 'that could signal' लंबे phrase के बाद आता है। परंतु 'that' signatures के लिए सही प्रयुक्त है और 'an imminent eruption' सही कर्म है।'S' seemed wrong because 'that could signal' follows a long phrase. But 'that' correctly refers to the signatures, and 'an imminent eruption' is a correct object.
