instruction:
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.
question:
passage: London Bridge is a central London railway terminus and connected London Underground station in Southwark, occupying a large area on three levels immediately south-east of London Bridge and 1.6 miles (2.6 km) east of Charing Cross. The main line station is the oldest railway station in London fare zone 1 and one of the oldest in the world having opened in 1836. It is one of two main line termini in London to the south of the River Thames, the other being Waterloo.
 question: is there a tube station at london bridge?
answer:
Yes


question:
passage: A passphrase is a sequence of words or other text used to control access to a computer system, program or data. A passphrase is similar to a password in usage, but is generally longer for added security. Passphrases are often used to control both access to, and operation of, cryptographic programs and systems, especially those that derive an encryption key from a passphrase. The origin of the term is by analogy with password. The modern concept of passphrases is believed to have been invented by Sigmund N. Porter in 1982.
 question: is a passphrase the same as a password?
answer:
No


question:
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 dot product the same as cross product?
answer:

No
