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 anxiety-producing situations. He had a hunch that anxiety-producing situations would broadly belong to two categories - inter-personal-evaluative and physically-threatening. His tool, assessing situation-specific anxiety, had 14 situations. For each situation, the subject was required to indicate on 11 five-point 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 un-rotated factors were extracted. Using Cattell’s scree plot, three factors were retained for rotation. The rotated factors had - small or moderate inter-factor 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.
