D. Grand CanalD. ग्रैंड कैनाल
Explanationव्याख्या
The correct answer is the Grand Canal.
According to the source, the Grand Canal of China is the world's longest man-made waterway.
The book further states that this waterway links the Yellow River and the Yangtze River.
Therefore the main source-supported revision chain is: Grand Canal — China — world's longest man-made waterway — connection between the Yellow River and Yangtze River.
This is a useful World GK question combining physical geography with a major human-made feature.
Corinth Canal, Kiel Canal and Suzhou Canal are distractors in the original PYQ.
The source does not describe those waterways in this entry, so their locations or dimensions have not been introduced as source-derived facts.
The link between two major Chinese river systems is particularly valuable because a future examination may describe the canal through the rivers it connects rather than directly asking for the longest man-made waterway.
Students should therefore retain both pieces of information together: the superlative and the river connection.
The source does not provide the canal's exact length, date of construction, dynastic history, route through individual provinces or UNESCO status in this explanation.
Those details should not be inferred as part of the source material.
Quick revision: China — Grand Canal — World's Longest Man-made Waterway — Yellow River + Yangtze River.
The question may be asked in reverse form, for example: 'The Grand Canal, the world's longest man-made waterway, is located in which country?' The source's printed solution is option (d), Grand Canal, and its explanation is consistent with that answer.
सही उत्तर Grand Canal है। स्रोत के अनुसार China का Grand Canal दुनिया का longest man-made waterway है। Book आगे बताती है कि यह waterway Yellow River और Yangtze River को link करता है। इसलिए main source-supported revision chain है: Grand Canal — China — World's Longest Man-made Waterway — Yellow River + Yangtze River Connection। यह World GK का useful question है क्योंकि इसमें physical geography और human-made feature दोनों combine होते हैं। Corinth Canal, Kiel Canal और Suzhou Canal original PYQ में distractors हैं। Source इस entry में इन canals के locations या dimensions explain नहीं करती, इसलिए उन्हें book-derived facts के रूप में add नहीं किया गया है। Yellow River और Yangtze River connection एक बहुत important clue है क्योंकि future exam direct superlative पूछने के बजाय river-linking description दे सकता है। इसलिए दोनों facts एक साथ याद रखें। Source Grand Canal की exact length, construction date, dynastic history, individual provinces या UNESCO-related details इस explanation में नहीं देती। इसलिए उन्हें outside knowledge से नहीं जोड़ा गया है। Quick revision: China — Grand Canal — Longest Man-made Waterway — Yellow River और Yangtze River को Link करता है। Reverse question भी possible है: Grand Canal किस country में है? Answer — China। Printed solution option (d), Grand Canal, है और explanation उसी को support करती है। इसलिए विकल्प (d) सही है।
