True - false questions

Indicate whether the following statements are true or false:

  • The industry standard resolution for printed images is 300 DPI (dots per inch)
    • True
      • Correct.
    • False
      • Incorrect. 300 DPI produces a good quality of printed image.
  • Vector graphics are suitable for diagrams and graphs
    • True
      • Correct.

    • True
      • Incorrect. Because PDFs are not easy to edit, they do not make it easy to adapt images or text for re-use - a core feature of OER.
    • False
      • Correct. Because PDFs are not easy to edit, they do not make it easy to adapt images or text for re-use - a core feature of OER.
  • You are free to re-use any svg file on the internet
    • True
      • Incorrect. Only files which are openly licensed or in the public domain can be re-used.
