Four friends - A, B, C and D - belong to an island, in which each person belongs to one of the three tribes - Truth tellers, Alternators and Liars.

Analysis:
- Given that each person made three statements, we need to carefully analyze the statements made by each person to determine who the liar(s) are.
Statements by A:
1. A states that C is either a Journalist or a Doctor.
2. A states that C is not a Truth teller.
3. A states that B is an Engineer.
Statements by B:
1. B's first statement is in the local language.
2. B states that at least one of his statements is false.
3. B's third statement is in the local language.
Statements by C:
1. C states that A is a Doctor.
2. C states that B's third statement is that D is a truth teller.
3. C states that D is neither a Journalist nor an Engineer.
Statements by D:
1. D states that C made exactly one true statement.
2. D states that exactly two of them are truth tellers.
3. D states that C is a Journalist.
Analysis of statements:
- From A's statements, we can see that C cannot be a Truth teller, as A states that C is not a Truth teller.
- From B's statements, we can see that at least one of B's statements is false, indicating that B is a liar.
- From C's statements, we can see that D is neither a Journalist nor an Engineer, which means D is a Doctor. This also confirms C is not a Truth teller.
- From D's statements, we can see that C made exactly one true statement, which implies that D is a liar.
Conclusion:
- Therefore, the liars in this scenario are A and D.
