Discussion
The types of information needed by scientist are :
(i) Experimental information
(ii) Know-why information
(iii) User information
(iv) Know-how information
Codes :
Answer: C
The answer is (i), (ii) and (iv) are correct.
Scientists need experimental information (data and results from experiments), know-why information (the theory and principles that explain phenomena) and know-how information (methods, techniques and procedures).
'User information' is information about users, which matters to librarians studying their clientele rather than to scientists in their own work, so the codes that include (iii) are wrong.
