Input: Article: Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.

Now answer this question: What types of new species can be introduced?

Output: The exotic organisms may be predators, parasites

Input: Article: Arguing against the absolutist position, Leibniz offers a number of thought experiments with the purpose of showing that there is contradiction in assuming the existence of facts such as absolute location and velocity. These arguments trade heavily on two principles central to his philosophy: the principle of sufficient reason and the identity of indiscernibles. The principle of sufficient reason holds that for every fact, there is a reason that is sufficient to explain what and why it is the way it is and not otherwise. The identity of indiscernibles states that if there is no way of telling two entities apart, then they are one and the same thing.

Now answer this question: What states that if there is no way of telling two entities apart, then they are one and the same thing?

Output: identity of indiscernibles

Input: Article: In 1996, Kerry faced a difficult re-election fight against Governor William Weld, a popular Republican incumbent who had been re-elected in 1994 with 71% of the vote. The race was covered nationwide as one of the most closely watched Senate races that year. Kerry and Weld held several debates and negotiated a campaign spending cap of $6.9 million at Kerry's Beacon Hill townhouse.

Kerry won re-election with 53 percent to Weld's 45 percent.

Now answer this question: Who ran against Kerry in 1996?
