Israel responded by what is termed here 'terrorist' tactics of the PLO in the 1970's by raiding PLO bases in neighboring Arab countries. It must be realized historically that Palestine used to belong to the Arab Palestinians ie it was their country and it was stolen by the British colonialists and sold to the rich Zionists for their so-called homeland. If the Israel govt really wanted to live in peace with the Palestinians and be slightly modest that they took away their country, then they wouldn't provoke them with settlements in the little land left that the Palestinians have on the Westbank and they would live in peace and harmony with them and Israel could have both Arabs and Jews living in harmony.
Your answer will be The purpose of the European Union was to promote greater social, economic harmony among the nations of Western Europe.
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.

I believe the answer is B. I think it's B because I just studied this subject in school and it sounds best
