Task: Question Answering
Input (English): Passage: As the British fleet closed with the opposing combined fleets of France and Spain, Lord Nelson signalled all the necessary battle instructions to his ships. Aware of the momentousness of events to come, Lord Nelson felt that something extra was required. He instructed his signal officer, Lieutenant John Pasco, to signal to the fleet, as quickly as possible, the message "England confides that every man will do his duty." Pasco suggested to Nelson that expects be substituted for confides (i.e. is confident), since the former word was in the signal book, whereas confides would have to be spelt out letter-by-letter. Nelson agreed to the change (even though it produced a less trusting impression):
His Lordship came to me on the poop, and after ordering certain signals to be made, about a quarter to noon, he said, 'Mr. Pasco, I wish to say to the fleet, ENGLAND CONFIDES THAT EVERY MAN WILL DO HIS DUTY' and he added 'You must be quick, for I have one more to make which is for close action.' I replied, 'If your Lordship will permit me to substitute the confides for expects the signal will soon be completed, because the word expects is in the vocabulary, and confides must be spelt,' His Lordship replied, in haste, and with seeming satisfaction, 'That will do, Pasco, make it directly.'
Thus, at around 11:45 a.m. on 21 October 1805, the signal was sent. The exact time the signal was sent is not known (one account puts it as early as 10:30), as the message was repeated throughout the fleet, but Pasco puts it at "about a quarter to noon" and logs from other ships of the line also put it close to this time. 
Question: What is the last name of the person who replied,  'That will do, Pasco, make it directly.'?
Output (English): Nelson.
