Explanation:

The text mentions that communism has moved from subversion to armed invasion and war (so the use of armed forces to spread communism is a concern). It also states that the attack defied UN orders (North Korea's defiance of UN orders is a concern). And it says the occupation of Formosa (Taiwan) by communist forces would be a threat (the threat of a communist invasion of Taiwan (Formosa) is a concern). The potential for instability in the Pacific area is also implied as the occupation of Formosa would be a threat to the Pacific area. The text says communism has passed beyond subversion (so the use of subversive tactics is not a current concern as per the text's emphasis on armed invasion now).

Answer:

the use of armed forces to spread communism, the threat of a communist invasion of Taiwan (Formosa), North Korea's defiance of UN orders, the potential for instability in the Pacific area
