The correct code snippet is option A. Here's the explanation: "FlND(City, 'New York') > checks if the string 'New York' is found within the 'City' variable. If it is, the function returns a positive number indicating the position of the first occurrence. The code then assigns 'NY to 'State'. The code uses similar logic for 'Los Angeles' and 'Chicago'. The "else" statement catches all other cities not matching the specified conditions and assigns 'Other' to 'State' Option B uses a wrong condition for the FIND function, as it should check for a positive return value, not just a non-zero value. Options C and E check for a specific position of the found string, which is not correct. Option D uses the 'ne' operator (not equal to) instead of the '>' operator (greater than), which results in an incorrect check for the FIND function. Only option A correctly implements the desired logic.

The correct answer is option C. The ORDER= option within the PROC EXPORT statement allows you to specify the order of variables in the exported file. It takes a list of variables enclosed in parentheses- The correct syntax is ORDER=(Product_Name Product_lD Price). Option A exports the data without specifying an order- Option B and D specify invalid ORDER= options. Option E specifies the ASCENDING order, which is not what the question asks.

Both options B and E correctly filter the observations based on the total amount and the order date. Option B uses the WHERE statement with the BETWEEN operator to filter the observations based on the order date, while Option E uses the IF statement with the BETWEEN operator and the OUTPUT statement to explicitly output the desired observations. Option A uses the IF statement but doesn't include the BETWEEN operator for the order date. Option C has incorrect logic for nested IF statements- Option D includes two WHERE statements, which isn't the correct syntax for filtering multiple conditions.

The correct option is A. The difference between two SAS date values directly yields the number of days between them. Option B uses the INTCK function to count intervals, which is not the most direct way to calculate the difference in days. Option C uses the INTCK function with the dates in reverse order, which would yield the incorrect result. Option D adds 1 to the difference, which is incorrect. Option E uses the INTCK function and subtracts 1 which would give the wrong number of days.

Both 'KEEP=' and 'DROP=' options can be used within the SET statement to select specific variables for output- Option A uses 'KEEP=' to explicitly include the desired variables, Option B uses 'DROP=' to exclude the unwanted variables, and Option D combines 'SET' and 'DROP=' for the same purpose- Option C is incorrect because 'KEEP=' must be used within the SET statement for variable selection. Option E is incorrect because it focuses on renaming variables instead of selecting them for output.
