None of the other choices In the DATA step, what happens if a MERGE statement is used without a BY statement? Select one: a. The observations in the input data sets are appended /concatenated O b. There is an error in combining the input data sets C. None of the other choices d. The observations in the input data sets are linked on the common variable(s)

Answer 1

1) Option A - Soak inthe sunshine.

Here, the syntax given is to print the string vlaue. The string which is represented within single quotes is displayed as same and symbol || indicates one space is in between two strings. But, | indicates there is no space between two strings.

So, output os displayed as Soak inthe sunshine-option A.

2) Option A - Observations in input datasets will be appended or concatenated.

Generally, BY statement is used to match the records that have a common variable. If by statement is not used, it doesnot perform matching. Then, observations in two data sets are combined based on their position. If by is not used, then common variable will gets overwrite.

So, option A is true, where data sets will be concatenated.
