You will be given a context and a verb separated with a newline character, and you have to answer if the given verb is a negation or not. A verb is a negation if it is not going to exist, not happen, or has no effect. The output should be "Yes" if the verb is a negation and "No" otherwise.
Example: Only the government of the United States can decide if it prefers this variant, continued the letter, which Castro read on a state television station broadcast. Gonzalez for months refused requests by Elian's Miami relatives to go to the United States to (claim) the boy.  
 Verb: claim
Example solution: Yes
Example explanation: This is a good example. Gonzalez refused to "claim" the boy. So, the claim didn't happen and it's a negation.

Problem: A State Department duty officer said she had no information on a threat to Elian and was unaware of Castro's remarks. In Miami, the boy's great-uncle, Lazaro Gonzalez, denied that he would (send) Elian out of the country, or that he himself would leave.  
 Verb: send

Solution: Yes
