Question

background information: this is from a statement made by an israeli foreign minister to the un security council on june 6, 1967 (the second day of the six - day war).
now there could be no doubt about what was intended for us. with my very ears i heard president nassers speech on 26 may. he said:
\we intend to open a general assault against israel. this will be total war. our basic aim will be to destroy israel.\
on 2 june, the egyptian commander in sinai, general mortagi, published his order of the day, calling on his troops to wage a war of destruction against israel. here, then, was a systematic, overt, proclaimed design at politicide, the murder of a state.
the policy, the arms, the men had all been brought together, and the state thus threatened with collective assault was itself the last sanctuary of a people which had seen six million of its sons exterminated by a more
why is foreign minister eban giving this stateme
to convince the members of the united nation
egypt had taken the first shot
to persuade the united nations to permit israel
establish a homeland in palestinian
to explain why israel was justified in attacking the
egyptian forces
to assure the united nations that israel only
intended to do battle for four more days

Explanation:

The text shows that Israel's Foreign Minister Eban is presenting evidence (Nasser's speech about intending to destroy Israel, Egyptian General's call for a war of destruction) to the UN. This is likely to justify Israel's actions. Since Israel was under threat of destruction (as per the presented statements), attacking Egyptian forces could be seen as a defensive or justifiable move. The other options: There's no indication Egypt took the first - shot in the text (it's about Egypt's intent), Israel already had a homeland by 1948 so the UN - permission - for - homeland option is wrong, and there's no mention of a 4 - day battle assurance.

Answer:

to explain why Israel was justified in attacking the Egyptian forces
