In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
Polytechnics generally focused on what in the beginning?, Context: Polytechnics were tertiary education teaching institutions in England, Wales and Northern Ireland. Since 1970 UK Polytechnics operated under the binary system of education along with universities. Polytechnics offered diplomas and degrees (bachelor's, master's, PhD) validated at the national level by the UK Council for National Academic Awards CNAA. They particularly excelled in engineering and applied science degree courses similar to technological universities in the USA and continental Europe. The comparable institutions in Scotland were collectively referred to as Central Institutions. Britain's first Polytechnic, the Royal Polytechnic Institution later known as the Polytechnic of Central London (now the University of Westminster) was established in 1838 at Regent Street in London and its goal was to educate and popularize engineering and scientific knowledge and inventions in Victorian Britain "at little expense." The London Polytechnic led a mass movement to create numerous Polytechnic institutes across the UK in the late 19th Century. Most Polytechnic institutes were established at the centre of major metropolitan cities and their focus was on engineering, applied science and technology education.

Ex Output:
engineering, applied science and technology education


Ex Input:
An object that is fixed in place and cannot move is said to be also what?, Context: The normal force is due to repulsive forces of interaction between atoms at close contact. When their electron clouds overlap, Pauli repulsion (due to fermionic nature of electrons) follows resulting in the force that acts in a direction normal to the surface interface between two objects.:93 The normal force, for example, is responsible for the structural integrity of tables and floors as well as being the force that responds whenever an external force pushes on a solid object. An example of the normal force in action is the impact force on an object crashing into an immobile surface.

Ex Output:
immobile


Ex Input:
Which side of a CD is easier to fix?, Context: CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.

Ex Output:

Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing
