In this task you will be given a claim and a perspective. You should determine whether that perspective supports or undermines the claim. If the perspective could possibly convince someone with different view, it is supporting, otherwise it is undermining.

Example Input: claim: Gay marriage should be legal.
 perspective: The institution of marriage cannot be harmed by giving more people the freedom to marry and it may become the case that heterosexual marriage is less stable than same-sex marriage. 
Example Output: support

Example Input: claim: Transparency is necessary for security.

Example Output: support
