Answer:
D. Positive information would have a greater impact on Tamara's impression than negative information would have.
Explanation: Tamara's impression about Aisha is based on the interpretation and organization of some observable traits or information when they both met, which is called schema. Thus it allowed Tamara to quickly conclude and conceive a posture thought about Aisha. Similarly, Tamara could have equally developed a negative impression about Aisha if her actions or behavior was unfriendly when they first met. As first impression usually sticks longer, it could be truly difficult to change Tamara's impression of Aisha.
However, both Positive and Negative information would have the same effect or impact on Tamara's impression of Aisha according to the text, because they are just meeting for the first time and there is no reason according to the text why one information should weigh more than the other.
