The use of 'however' in statement 4 indicates that it must be preceded by a contrasting idea, and statement 1 provides that contrast. Therefore, 1 and 4 form a necessary pair. Statement 3 suggests a possible change in attitude, and this attitude is expressed in statement 1. Thus, 143 form a pair because 3 cannot precede 1. The negative attitude needs to be stated first, followed by the acknowledgment that your attitude may change once you realize the skill required for such music.
Statement 2 can only come at the beginning and not at the end. Hence, the correct sequence is 2143. This makes it an easy question.
