Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by the answer prefix 'A:', and the follow-up question has a prefix 'FOLLOWUP_Q:'.

CONTEXT: I assume you're making normal maki (nori side out) and not California rolls.Are you leaving a 1/2 inch or so of blank nori (no rice) on the outside edge (the edge that you roll last)? If you slightly wet the bare edge of the nori with a little water on your finger it should help it stick together. <sep> Q: How do I stop sushi rolls from opening up? A: leaving a 1/2 inch or so of blank nori (no rice) on the outside edge <sep> FOLLOWUP_Q: What is causing that to happen?
Yes

CONTEXT: Yes, you can freeze parmesan cheese. Even without freezing, Parmesan is very durable since the low water and high salt content prevents mould from growing. The younger varieties may be more prone to mould growth (having a higher water content), but I've kept ripe Parmesan (30-36 months) for at least a year in the fridge without problems (and it would probably have stayed good much longer). Just remember to keep it wrapped in paper, not in a sealed plastic container to prevent a buildup of condensation. <sep> Q: Can I freeze Parmesan?
Yes

CONTEXT: It might be there for body, but more likely for the umami kick that tomato past helps with. I bet you could leave it out with no ill effect...otherwise, try some ketchup. You could also open the small can, use what you need and put the rest in a baggy in the freezer. <sep> Q: What can I substitute for tomato paste to thicken a marinade? A: try some ketchup <sep> FOLLOWUP_Q: Will ketchup make the marinade too sweet?
No
