A. The idea of partitioning Palestine between the settler movement of Zionism, and later the state of Israel and the indigenous population of Palestine is not new.
B. For more than 50 years, well-intentioned and more cynical, local and external actors involved in the attempts to bring peace and reconciliation to historical Palestine have religiously adhered to the two-state solution as the only way forward.
C. It was first offered by the British in 1937 and rejected by the Palestinians already then.
D. The Zionist movement was hardly 50 years old and was already offered by the new British occupiers of Palestine, a chunk of the Palestinian homeland as a future state.

The context of the given paragraph is regarding the ongoing war between Israel and Palestine and the theories involved in bringing peace to the war-torn state. A number of theories given to partition the state of Palestine which involves the Zionism movement and the new England settlers have gone in vein. Now, after carefully reading the statements it is evident that statement (A) should not be the first sentence of the passage as it directly delves into two propositions. Statement (B) should be the first sentence of the passage as it states about the fifty years of attempts to bring peace in Palestine and the two-state theory. It gives us the base of our discussion. Statement (A) should follow statement (B), as already mentioned this gives us the detailed discussion of the two-state theories. Statement (C) follows (A), letting us know that one of these theories was offered by the British in 1937 and rejected by the Palestinians already then. Statement (D) tells us about the first theory of Zionism which was hardly 50 years old and was already offered by the new British occupiers of Palestine and thus concludes the passage. If we exchange A and B, we get a logical paragraph. Proper sequence becomes: BACD. Hence, option C is the correct answer.
