QUES: Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000–400 cm−1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm−1).
What happens to a molecule if an oscillation results in a dipole being changed?

ANS: it will absorb a photon that has the same frequency

QUES: Further problems hampered the Arctic project after the commencement of drilling in 2012, as Shell dealt with a series of issues that involved air permits, Coast Guard certification of a marine vessel and severe damage to essential oil-spill equipment. Additionally, difficult weather conditions resulted in the delay of drilling during mid-2012 and the already dire situation was exacerbated by the "Kulluk" incident at the end of the year. Royal Dutch Shell had invested nearly US$5 billion by this stage of the project.
Who damaged essential oil-spill equipment?

ANS: unanswerable

QUES: The trophy comes in three parts - the cup itself, plus a lid and a base. There have been two designs of trophy in use, but five physical trophies have been presented. The original trophy, known as the "little tin idol", was 18 inches high and made by Martin, Hall & Co. It was stolen in 1895 and never recovered, and so was replaced by an exact replica, used until 1910. The FA decided to change the design after the 1909 winners, Manchester United, made their own replica, leading the FA to realise they did not own the copyright. This new, larger design was by Messers Fattorini and Sons, and was used from 1911. In order to preserve this original, from 1992 it was replaced by an exact replica, although this had to be replaced after just over two decades, after showing wear and tear from being handled more than in previous eras. This third replica, first used in 2014, was built heavier to withstand the increased handling. Of the four surviving trophies, only the 1895 replica has entered private ownership.
What is the  parts of the trophy? 

ANS: - the cup itself, plus a lid and a base

QUES: Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods.
 During which prehistoric age was the Greek language rejected?
