Answer: D
Reasoning: The only correct answer is that the number of
observations for each record must be the same.
isn't that supposed to be the number of records for each observation must be the same.
i know it is not A.
D is not either and i agree with GG.
so it is either B or C.
but in order to read multiple records to create a single observation, you do not have to use #n pointer. you can simply split the input statements into a few lines to match the records you want to read in. if that is what B is trying to say, then B is the answer.
I don't like the way the question is worded but it is D. Try messing with the number of variables in the below code and it won't work as intended:
data test;
infile cards;
input name $ age1-age6;
cards;
gus 1 2 3
4 5 6
jack 1 2 3
4 5 6
;
run;
It couldn't be C, since to read multiple records sequentially you have to use / line pointer control, not necessary # pointer control. I would say, that number of records must be the same for each observation, but there is not such an answer.
D, but the question has a typo which should be "D) The number of records for each observation must be the same"
