I thought my grammar was one of my strong points; however, I must be wrong. Can anyone offer their opinion on the following sentence.

The soft tissue and bowel lumen (measure, measures) 8 cm in length and (has,have) a 6 cm x 3.5 margin of colostomy deep to the subcutaneous tissue.

which word in the parentheses should I use?

Thanks alot.

I suspect this professional web site is not for asking test questions. This is a test question, and it is unprofessional to ask it. Tests are an assessment of what you know and what you will transcribe on the job, not what your peers and colleagues know.
