Final answer:
Increased tolerance and continued use despite problems are good clues to alcohol dependency.
Step-by-step explanation:
The good clue to alcohol dependency while taking an alcohol drug history is a. Increased tolerance and withdrawal symptoms when abstinence is attempted and b. Continued use despite experiencing problems that result from drinking. Increased tolerance means that the person needs to consume larger amounts of alcohol to achieve the same effects as before, while withdrawal symptoms occur when the person stops drinking and experiences negative physical and psychological symptoms. Additionally, the continued use of alcohol despite experiencing problems related to drinking is a strong indication of alcohol dependency.
