Problem: Please answer a question about the following article about Dialect:

All Lebanese laws are written in the standard literary form of Arabic, though parliamentary debate may be conducted in Lebanese Arabic.
During the Lebanese Civil War, what language did Lebanese Christians sometimes use officially?
A: Lebanese Arabic
Problem: Please answer a question about the following article about Hellenistic period:
Modern interpretations see this period as a civil war between Hellenized and orthodox forms of Judaism. Out of this revolt was formed an independent Jewish kingdom known as the Hasmonaean Dynasty, which lasted from 165 BCE to 63 BCE. The Hasmonean Dynasty eventually disintegrated in a civil war, which coincided with civil wars in Rome. The last Hasmonean ruler, Antigonus II Mattathias, was captured by Herod and executed in 37 BCE. In spite of originally being a revolt against Greek overlordship, the Hasmonean kingdom and also the Herodian kingdom which followed gradually became more and more hellenized. From 37 BCE to 6 CE, the Herodian dynasty, Jewish-Roman client kings, ruled Judea. Herod the Great considerably enlarged the Temple (see Herod's Temple), making it one of the largest religious structures in the world. The style of the enlarged temple and other Herodian architecture shows significant Hellenistic architectural influence.
Who was the last Hasmonean ruler?
A:
Antigonus II Mattathias
