Instructions for the questions below. Read the following paragraph and answer the five questions that follow:
An anxiety researcher, working in the interaction model of anxiety, wanted to factor analyzes anxietyproducing situations. He had a hunch that anxietyproducing situations would broadly belong to two categories  interpersonalevaluative and physicallythreatening. His tool, assessing situationspecific anxiety, had 14 situations. For each situation, the subject was required to indicate on 11 fivepoint rating scales as to how he or she would respond in that situation. Thus for each situation scale, the minimum score would be 11 and the maximum score would be 55. The correlation matrix among the 14 situation scales was formed. Two factor analyses were carried out on this correlation matrix. In the first factor analysis, unities were retained in the diagonal spaces of the correlation matrix and the unrotated factors were extracted. Using Cattell’s scree plot, three factors were retained for rotation. The rotated factors had  small or moderate interfactor correlations. In the second factor analysis, appropriate communality estimates were inserted in the diagonal spaces of the correlation matrix and the three factors were rotated using the same rotation method, used in the same factor analysis.
