The presence of more vertical lines in the array does not affect the time it takes the subject to locate the horizontal line. The task only requires the subject to locate one specific line, and the number of other lines in the array is irrelevant. The similarity of color between the lines is also not likely to be a significant factor in the time it takes to locate the horizontal line. The darkness of the vertical lines may be a potential distracting factor, but it is not specified in the question and cannot be assumed to have a consistent effect on all subjects.
