Input: Read this: YouTube entered into a marketing and advertising partnership with NBC in June 2006. In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for US viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney. In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners. In January 2010, YouTube introduced an online film rentals service, which is available only to users in the US, Canada and the UK as of 2010. The service offers over 6,000 films.

Input: Read this: Regardless of the way the tension between universities, individual scientists, and the scientific revolution itself is perceived, there was a discernible impact on the way that university education was constructed. Aristotelian epistemology provided a coherent framework not simply for knowledge and knowledge construction, but also for the training of scholars within the higher education setting. The creation of new scientific constructs during the scientific revolution, and the epistemological challenges that were inherent within this creation, initiated the idea of both the autonomy of science and the hierarchy of the disciplines. Instead of entering higher education to become a "general scholar" immersed in becoming proficient in the entire curriculum, there emerged a type of scholar that put science first and viewed it as a vocation in itself. The divergence between those focused on science and those still entrenched in the idea of a general scholar exacerbated the epistemological tensions that were already beginning to emerge.
Question: Where did students after the scientific revolution put science on the scale of importance?

Output: first

Input: Read this: The cloth or fiber material used, resin material, and the cloth to resin ratio determine the laminate's type designation (FR-4, CEM-1, G-10, etc.) and therefore the characteristics of the laminate produced. Important characteristics are the level to which the laminate is fire retardant, the dielectric constant (er), the loss factor (t), the tensile strength, the shear strength, the glass transition temperature (Tg), and the Z-axis expansion coefficient (how much the thickness changes with temperature).
Question: The shear sector is one of the important what?

Output: unanswerable
