Assertion (A) : Indexing periodicals provide brief summary of articles.
Reason (R) : They provide only list of articles along with the title, authors and other bibliographic details of articles.

  • A.Both (A) and (R) are true
  • B.Both (A) and (R) are false
  • C.(A) is true but (R) is false
  • D.(A) is false but (R) is true

Answer: D

(A) is false but (R) is true.

Indexing periodicals list articles with their bibliographic details, such as title, authors, journal, volume and pages, under subject headings. They do not summarise the content, so A is false.

Summaries of articles are what abstracting periodicals provide. Statement R correctly describes what an indexing periodical gives, so it is true. That rules out both options that call A true and the option calling R false.
