Input: Article: For instance, to look up the character where the sound is not known, e.g., (pine tree), the user first determines which part of the character is the radical (here ), then counts the number of strokes in the radical (four), and turns to the radical index (usually located on the inside front or back cover of the dictionary). Under the number "4" for radical stroke count, the user locates , then turns to the page number listed, which is the start of the listing of all the characters containing this radical. This page will have a sub-index giving remainder stroke numbers (for the non-radical portions of characters) and page numbers. The right half of the character also contains four strokes, so the user locates the number 4, and turns to the page number given. From there, the user must scan the entries to locate the character he or she is seeking. Some dictionaries have a sub-index which lists every character containing each radical, and if the user knows the number of strokes in the non-radical portion of the character, he or she can locate the correct page directly.

Now answer this question: What gives remaining stroke numbers?

Output: sub-index

Input: Article: In 1919, the frustrations caused by delays to Irish home rule led members of Sinn Fein, a pro-independence party that had won a majority of the Irish seats at Westminster in the 1918 British general election, to establish an Irish assembly in Dublin, at which Irish independence was declared. The Irish Republican Army simultaneously began a guerrilla war against the British administration. The Anglo-Irish War ended in 1921 with a stalemate and the signing of the Anglo-Irish Treaty, creating the Irish Free State, a Dominion within the British Empire, with effective internal independence but still constitutionally linked with the British Crown. Northern Ireland, consisting of six of the 32 Irish counties which had been established as a devolved region under the 1920 Government of Ireland Act, immediately exercised its option under the treaty to retain its existing status within the United Kingdom.

Now answer this question: What treaty was signed after the Anglo-Irish War?

Output:
Anglo-Irish Treaty
