Input: Read this: John was incensed about what he perceived as an abrogation of his customary right as monarch to influence the election. He complained both about the choice of Langton as an individual, as John felt he was overly influenced by the Capetian court in Paris, and about the process as a whole. He barred Langton from entering England and seized the lands of the archbishopric and other papal possessions. Innocent set a commission in place to try to convince John to change his mind, but to no avail. Innocent then placed an interdict on England in March 1208, prohibiting clergy from conducting religious services, with the exception of baptisms for the young, and confessions and absolutions for the dying.
Question: John felt Langton was overly influenced by what?

Output: the Capetian court in Paris

Input: Read this: Notably, the most broadly influential innovation of 20th-century American tort law was the rule of strict liability for defective products, which originated with judicial glosses on the law of warranty. In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products. The American Law Institute subsequently adopted a slightly different version of the Greenman rule in Section 402A of the Restatement (Second) of Torts, which was published in 1964 and was very influential throughout the United States. Outside the U.S., the rule was adopted by the European Economic Community in the Product Liability Directive of July 1985 by Australia in July 1992 and by Japan in June 1994.
