Assertion (A): Dope test is used to estimate the level of blood alcohol by analysing the breath of persons drinking alcohol.
Reason (R): A drunken person usually feels tense and less talkative.
Both A and R are incorrect
Dope test is a blood test to know whether a person taking part in a competition had used any drug to make their performance better. Dope test is not related with alcohol.
Alcohol has a relaxing effect on the body. Hence, the person feels less tense and less inhibited and so ends up talking more.
Therefore, assertion and reason both are incorrect.
