Input: Article: Although Whig grandees such as Portland and Fitzwilliam privately agreed with Burke's Appeal, they wished he had used more moderate language. Fitzwilliam saw the Appeal as containing "the doctrines I have sworn by, long and long since". Francis Basset, a backbench Whig MP, wrote to Burke: "...though for reasons which I will not now detail I did not then deliver my sentiments, I most perfectly differ from Mr. Fox & from the great Body of opposition on the French Revolution". Burke sent a copy of the Appeal to the king and the king requested a friend to communicate to Burke that he had read it "with great Satisfaction". Burke wrote of its reception: "Not one word from one of our party. They are secretly galled. They agree with me to a title; but they dare not speak out for fear of hurting Fox. ... They leave me to myself; they see that I can do myself justice". Charles Burney viewed it as "a most admirable book—the best & most useful on political subjects that I have ever seen" but believed the differences in the Whig Party between Burke and Fox should not be aired publicly.

Now answer this question: Who thought Burke should have written in a more moderate tone?

Output: Portland and Fitzwilliam

Input: Article: The most extreme case was the Soviet Union, and this model may still be followed in some countries: it was a separate service, on a par with the navy or ground force. In the Soviet Union this was called Voyska PVO, and had both fighter aircraft and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently these became part of the air force and ground forces respectively

Now answer this question: What two systems did Voyska PVO have?

Output:
fighter aircraft and ground-based systems
