In each question, you are given certain data followed by two statements. For answering the questions:

Mark a, if both the statements together are insufficient to answer the question.

Mark b, if any one of the two statements is sufficient to answer the question.

Mark c, if each statement alone is sufficient to answer the question.

Mark d, if both the statements together are sufficient to answer the question, but neither statement alone is sufficient.

If a, b, c are integers, is $(a - b + c)> (a + b - c)$?

1. b is negative

2. c is positive.

- if both the statements together are insufficient to answer the question.
- if any one of the two statements is sufficient to answer the question.
- if each statement alone is sufficient to answer the question.
- if both the statements together are sufficient to answer the question, but neither statement alone is sufficient.
