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.

Q: passage: In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate x is x − 4x + 7. An example in three variables is x + 2xyz − yz + 1.
 question: does a polynomial have to have a variable?

A: Yes

Q: passage: In a simple case such as an object resting upon a table, the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of the object), that is, N = m g (\displaystyle N=mg) , where m is mass, and g is the gravitational field strength (about 9.81 m/s on Earth). The normal force here represents the force applied by the table against the object that prevents it from sinking through the table and requires that the table is sturdy enough to deliver this normal force without breaking. However, it is easy to assume that the normal force and weight are action-reaction force pairs (a common mistake). In this case, the normal force and weight need to be equal in magnitude to explain why there is no upward acceleration of the object. For example, a ball that bounces upwards accelerates upwards because the normal force acting on the ball is larger in magnitude than the weight of the ball.
 question: is the normal force equal to the force of gravity?

A: Yes

Q: passage: Most of Facebook's acquisitions have primarily been ``talent acquisitions'' and acquired products are often shut-down. Facebook CEO Mark Zuckerberg has stated in 2010 that ``We have not once bought a company for the company. We buy companies to get excellent people... In order to have a really entrepreneurial culture one of the key things is to make sure we're recruiting the best people. One of the ways to do this is to focus on acquiring great companies with great founders.'' The Instagram acquisition, announced on 2012-04-09, appears to have been the first exception to this pattern. While continuing with a pattern of primarily talent acquisitions, other notable product focused acquisitions include the $19 billion WhatsApp acquisition and the $2 billion Oculus VR acquisition.
 question: is facebook and instagram owned by the same company?

A:
Yes
