This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Passage: In January 1918, Romanian forces established control over Bessarabia as the Russian Army abandoned the province. Although a treaty was signed by the Romanian and Bolshevik Russian governments following talks between 5 and 9 March 1918 on the withdrawal of Romanian forces from Bessarabia within two months, on 27 March 1918 Romania formally attached Bessarabia to its territory, based on a resolution passed by the local assembly of that territory on its unification with Romania. Romania officially made peace with the Central Powers by signing the Treaty of Bucharest on 7 May 1918. Under the treaty, Romania was obliged to end the war with the Central Powers and make small territorial concessions to Austria-Hungary, ceding control of some passes in the Carpathian Mountains, and to grant oil concessions to Germany. In exchange, the Central Powers recognised the sovereignty of Romania over Bessarabia. The treaty was renounced in October 1918 by the Alexandru Marghiloman government, and Romania nominally re-entered the war on 10 November 1918. The next day, the Treaty of Bucharest was nullified by the terms of the Armistice of Compiegne. Total Romanian deaths from 1914 to 1918, military and civilian, within contemporary borders, were estimated at 748,000.

Passage: France in the Ancien Regime covered a territory of around 200,000 square miles , and supported 22 million people in 1700. At least 96% of the population were peasants. France had the largest population in Europe, with European Russia second at 20 million. Britain had nearly six million, Spain had eight million, and the Austrian Habsburgs had around eight million. Russia was the most populated European country at the time. France's lead slowly faded after 1700, as other countries grew faster.

Passage: The Atlantic Ocean and the warming influence of the Gulf Stream affect weather patterns in Ireland. Temperatures differ regionally, with central and eastern areas tending to be more extreme. However, due to a temperate oceanic climate, temperatures are seldom lower than 5C in winter or higher than 26C in summer. The highest temperature recorded in Ireland was 33.3C on 26 June 1887 at Kilkenny Castle in Kilkenny, while the lowest temperature recorded was 19.1C at Markree Castle in Sligo. Rainfall is more prevalent during winter months and less so during the early months of summer. Southwestern areas experience the most rainfall as a result of south westerly winds, while Dublin receives the least. Sunshine duration is highest in the southeast of the country. The far north and west are two of the windiest regions in Europe, with great potential for wind energy generation.Ireland normally gets between 1100 and 1600 hours of sunshine each year, most areas averaging between 3.25 and 3.75 hours a day. The sunniest months are May and June, which average between 5 and 6.5 hours per day over most of the country. The extreme southeast gets most sunshine, averaging over 7 hours a day in early summer. December is the dullest month, with an average daily sunshine ranging from about 1 hour in the north to almost 2 hours in the extreme southeast. The sunniest summer in the 100 years from 1881 to 1980 was 1887, according to measurements made at the Phoenix Park in Dublin; 1980 was the dullest.
Question: Which year was the sunniest summer, 1887 or 1980?
