'TechXtra' is a ................

(i) Free Gateway Service
(ii) Commercial Gateway Service
(iii) Learning resources in Engineering, Mathematics and Computing
(iv) Source to find articles, books and industrial new

  • A.(i), (ii) and (iii) are true
  • B.(ii), (iii) and (iv) are true
  • C.(i), (iii) and (iv) are true
  • D.(i), (iii) and (iv) are false

Answer: C

TechXtra is a free gateway to learning resources and to articles, books and industry news, so the answer is (i), (iii) and (iv) are true.

TechXtra, run by Heriot-Watt University in Edinburgh, was a free service that brought together resources in engineering, mathematics and computing. It let users find articles, books, technical reports, theses, learning and teaching resources, and the latest industry news, through one search.

Because it was free, (ii) 'Commercial Gateway Service' is wrong, which rules out the two options that include (ii). The last option reverses the verdict by calling (i), (iii) and (iv) false, so it is wrong too.
