UGC NET Questions (Paper – 1)

Statements A, B, C, D and E correctly summarise the relationship between the Internet and the web, as well as tools and protocols. The web runs over the Internet, browsers access pages using URLs and HTTP/HTTPS, and search engines index content to support retrieval. Statement F is false because the Internet is a distributed network of many interconnected devices, not a single central computer. Therefore the true set consists of A, B, C, D and E only.

Option A:
Option A is correct because it includes all accurate statements about how the web operates over the Internet and how users access resources. It excludes the central-computer misconception in F, which contradicts the distributed nature of the Internet.

Option B:
Option B is incorrect because it omits E, thereby ignoring the important role of search engines in helping users navigate the vast web content. While A, B, C and D are true, the set does not contain all correct statements.

Option C:
Option C is incorrect because it adds F, which misrepresents the Internet architecture by treating it as a single machine. Mixing a false statement with true ones means this combination cannot be accepted.

Option D:
Option D is incorrect because it leaves out A and therefore does not explicitly describe what the World Wide Web is. Although B, C, D and E are correct, omitting A makes the description incomplete.

Statement C is the only wrong statement because modern search engines do not order results simply by alphabetical order of site names. They use complex ranking algorithms based on relevance, content and many other factors. Statements A, B and D correctly describe crawling, phrase searching and advanced filtering capabilities. Hence, the correct option is the one that chooses only statement C as wrong.

Option A:
Option A is incorrect because it groups A and C as wrong statements. Statement A is true since crawlers or spiders are indeed used for indexing pages. Labeling this as wrong contradicts how search engines build their indexes.

Option B:
Option B is correct because it isolates C as the sole wrong statement. It accepts that quotation marks can enforce phrase matching and that advanced search options enable filtering. Recognising C as the only incorrect claim aligns with actual search engine behaviour.

Option C:
Option C is incorrect because it combines A, B and C as wrong statements. Both A and B are accurate descriptions of search engine features, and only C is false. By including true statements in the wrong set, this combination fails.

Option D:
Option D is incorrect because it lists B, C and D as wrong, even though B and D are correct. Phrase searching and advanced search filters are standard features of modern search engines. Mixing correct statements with a wrong one makes the option invalid.

Statements A, B and D correctly explain the roles of search engines and subject gateways, while statement C is false. Search engines use automated crawlers and do not always judge academic quality, whereas subject gateways are curated by experts for specific disciplines. Using such gateways can improve the reliability of sources consulted by researchers. Therefore the combination A, B and D only is correct.

Option A:
Option A is incomplete because it includes only A and B and omits D. While A and B explain indexing and curation, they do not highlight the benefit of subject gateways for reliability, which D adds. Excluding D makes the answer less informative.

Option B:
Option B is correct because it combines statements that accurately differentiate broad, automated search engines from curated gateways and recognises their academic value. It excludes C, which wrongly assumes that all indexed pages are academically evaluated.

Option C:
Option C is incorrect because it lists only B and D and omits A. A provides the basic description of how general search engines work, so leaving it out gives an incomplete picture of web search.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts C. Since C misrepresents the indexing process, this combination cannot be considered correct.

Ranking algorithms consider factors such as keywords, links, freshness and user behaviour to estimate which pages match a query best. By presenting the most relevant pages at the top, search engines increase the likelihood that users will quickly find needed information. Although not perfect, this ranking is central to effective web searching. Thus, the main purpose is relevance-based ordering.

Option A:
This option accurately captures that the ranking algorithm’s aim is to prioritise pages that appear most relevant and useful for a given query. By pushing such pages towards the top of the results, search engines help users locate information efficiently.

Option B:
This option suggests that only advertisements are shown, which contradicts actual behaviour. Most search engines clearly separate paid ads from organic results and do not exclude genuine content.

Option C:
Randomly shuffling web pages would undermine user trust and make search engines unusable. Sophisticated algorithms are explicitly designed to avoid such randomness and instead approximate relevance.

Option D:
Deleting all academic pages would be the opposite of supporting information retrieval. Search engines index academic content along with other types of pages; they do not aim to remove it.
