<Problem>
 MAX_ANSWER = 3
 condition[1] = "calculate(a1) = -2"
 condition[2] = "calculate(a2) = 0"
 condition[3] = "calculate(b1) = 0"
 condition[4] = "calculate(b2) = 1"
</Problem>

<Answer 1>
 key = "condition[1] AND condition[2] AND condition[3] AND condition[4]"
 comment[1] = " Right. /n The mapping is a distension parallel to the x-axis /n with the coefficients a1 = -2, a2 = 0, b1 = 0 and b2 = 1."
</Answer 1>

<Answer 2>
 key = "NOT(condition[2] AND condition[4])"
 comment[1] = " Your answer is not right. /n The mapping is a distension parallel to the x-axis. /n So the y-coordinate stays constant. /n Just try again."
 comment[2] = " Your answer is not right. /n The mapping is a distension parallel to the x-axis /n with the coefficients a1 = -2, a2 = 0, b1 = 0 and b2 = 1."
</Answer 2>

<Answer 3>
 key = "1"
 comment[1] = " Your answer is not right. /n Just try again."
 comment[2] = " Your answer is not right. /n Just try again."
