In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.

Input: Consider Input: passage: In mathematics and vector algebra, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional space ( R 3 ) (\displaystyle \left(\mathbb (R) ^(3)\right)) and is denoted by the symbol × (\displaystyle \times ) . Given two linearly independent vectors a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) , the cross product, a × b (\displaystyle \mathbf (a) \times \mathbf (b) ) , is a vector that is perpendicular to both a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) and thus normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. It should not be confused with dot product (projection product).
 question: is the cross product of two normalized vectors normalized?

Output: Yes


Input: Consider Input: passage: Black Sails is an American historical adventure television series set on New Providence Island and a prequel to Robert Louis Stevenson's novel Treasure Island. The series was created by Jonathan E. Steinberg and Robert Levine for Starz.

Input: Consider Input: passage: An unlisted public company is a public company that is not listed on any stock exchange. Though the criteria vary somewhat between jurisdictions, a public company is a company that is registered as such and generally has a minimum share capital and a minimum number of shareholders. Each stock exchange has its own listing requirements which a company (or other entity) wishing to be listed must meet. Besides not qualifying to be listed, a public company may choose not to be listed on a stock exchange for a number of reasons, including because it is too small to qualify for a stock exchange listing, does not seek public investors, or there are too few shareholders for a listing. There is a cost to the listed entities, in the listing process and ongoing costs as well as in compliance costs such as the maintenance of a company register.
 question: can a company be public but not listed?


Output: Yes
