Answer:
A- Jihad --- A word meaning "struggle"
B- Orthodox --- Conforming to an approved doctrine
C- Martyr --- One who dies for his or her beliefs
D- Pogrom --- An organized massacre of a particular people
Explanation:
A- Jihad is an Arabic word meaning "struggle". It has an important place in the theology and ideology of Islam.
Some 'Muslim' extremists see jihad as a holy war against Islam's supposed enemies, but most Muslims reject it. The Islamic expression for 'holy war' is harb quds (the equivalent of the Crusade word in the Christian tradition).
B- The Orthodox term comes from the Greek orthos (right) and doxa (opinion). It means what is considered to conform to a doctrine considered to be the only true.
C- Martyr is one who dies for his or her principles, faith or belief. The word was originally used to describe a believer who is willing to suffer death for his faith rather than to reject it.
D- Pogrom refers to violent, sometimes organized gang brawls against members of religious, national, ethnic or minority groups. They are often associated with robbery and abuse, as well as murder or genocide.
