Final answer:
The statement about General Gamal Abdel Nasser being an Egyptian advocate of Pan-Arabism and the architect of the United Arab Republic is true. Nasser led the Free Officers Movement in a coup to assume control of Egypt, and he worked to unite Arab nations, briefly succeeding with Syria in forming the United Arab Republic in 1958.
Step-by-step explanation:
The statement that General Gamal Abdel Nasser was an Egyptian advocate of Pan-Arabism and the architect of the United Arab Republic is true. Nasser rose to prominence in Egypt after criticizing the government's failure in the Arab-Israeli conflict, and he led the Free Officers Movement, which resulted in a coup détat that deposed King Farouk in 1952. He became the Prime Minister of Egypt in 1954 and was a proponent of Pan-Arabism, an ideology that sought to unite all Arab nations.
Under Nasser's leadership, Egypt and Syria briefly united to form the United Arab Republic in 1958. This was a step toward the realization of Pan-Arabism, although the union dissolved after a coup in Syria in 1961. Nevertheless, Nasser remains a significant figure in Arab history for his efforts to create a pan-Arab state and for severing colonial ties with Western powers.
