Why must a program be tested again after finding and fixing an error?
A. to enable the beta testers to see the fix
B. to ensure that fixing the error did not cause another error
C. to run the program line by line
D. to check for extra comments in the code that may be left after debugging

Option B

Explanation:

The answer is option B " to ensure that fixing the error did not cause another error." Always check your program after you fix a issue to make sure you didn't start another issue or to find out if what you fixed in the program is being caused by something else. Doing so would reduce time and other issues in your program.

Hope this helps.

hey! im not 100 percent sure but im pretty sure that what you want to do is not possible : (

explanation:

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
