Directions: In the question below, the 1^st and the last (correctly ordered) sentences are numbered 1 and 6. The rest of the passage is split into four parts and named P, Q, R and S. These four parts are not given in the proper order. Chose the correct combination among the four alternatives given.

1. Cuba is an impoverished island that remains largely cut off from the world and lies about 4,500 miles from the West African nations where Ebola is spreading at an alarming rate. P. It still remains unclear how it would treat and evacuate Cubans who become sick. Q. Transporting quarantined patients requires sophisticated teams and specially configured aircraft. R. Yet, having pledged to deploy hundreds of medical professionals to the front lines of the pandemic, Cuba stands to play the most robust role among the nations seeking to contain the virus. S. The Cuban health care workers will be among the most exposed foreigners, and some could very well contract the virus. The World Health Organization will be directing the team of Cuban doctors.
2. As a matter of good sense and compassion, the American military, which now has about 550 troops in West Africa, should commit to giving any sick Cuban access to the treatment center the Pentagon built in Monrovia and to assisting with evacuation.
