Answers:
Break down the info you already have.
Arteries deliver blood AWAY from the heart.
Generally, vessels are named by their associated organ, so a pulmonary vessel is associated with the lung.
If you think about the vessels associated with your heart, low oxygenated (deoxygenated) blood flows from the heart to the lungs so that the blood can receive oxygen. Newly oxygenated blood then flows from the lungs back to the heart to be pumped into the rest of your body.
Therefore, a vessel coming TO with the lung leading AWAY from the heart would have very low oxygen content. Why else would blood go to the lung?
Blood will never have 100% of either oxygen or CO2, but you can have fractions of each. You will have more carbon dioxide/less oxygen blood going to the lungs via the pulmonary artery.
