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.

Question: 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 Compiègne. Total Romanian deaths from 1914 to 1918, military and civilian, within contemporary borders, were estimated at 748,000.
Question: How many days did the talks between Russians and Romanians last?

Answer: number


Question: Passage: In November 1944, after Greece was liberated from Germany, old drachmae were exchanged for new ones at the rate of 50,000,000,000 to 1. Only paper money was issued. The government issued notes of 1, 5, 10 and 20 drachmae, with the Bank of Greece issuing 50-, 100-, 500-, 1000-, 5000-, and 10,000-drachma notes. This drachma also suffered from high inflation. The government later issued 100-, 500-, and 1000-drachma notes, and the Bank of Greece issued 20,000-and 50,000-drachma notes. Third modern drachma coins The first issue of coins minted in 1954 consisted of holed aluminium 5-, 10- and 20-lepton pieces, with 50-lepton, 1-, 2-, 5- and 10-drachma pieces in cupro-nickel. A silver 20-drachma piece was issued in 1960, replacing the 20-drachma banknote, and also minted only in collector sets in 1965.  Coins in denominations from 50 lepta to 20 drachmae carried a portrait of Paul of Greece (1947–1964). New coins were introduced in 1966, ranging from 50 lepta to 10 drachmae, depicting Constantine II of Greece (1964–1974). A silver 30 drachma coin for the centennial of Greeces royal dynasty was minted in 1963.  The following year a non-circulating coin of this value was produced to commemorate the royal wedding.  The reverse of all coins was altered in 1971 to reflect the military junta which was in power from 1967 to 1974. This design included a soldier standing in front of the flames of the rising phoenix.
Question: What year was the non-circulating 30 drachma coin issued to commemorate the royal wedding?

Answer: date


Question: Passage: Following Jenkins' testimony and petitions from other West Indies merchants, the opposition in Parliament voted on 28 March 1738 to send "an Address" to the King, asking his Majesty to seek redress from Spain. More than one year later, all diplomatic means having been exhausted, on 10 July 1739 King George II authorised the Admiralty Board to seek maritime reprisals against Spain. On 20 July, Vice Admiral Edward Vernon and a fleet of warships departed Britain, bound for the West Indies, to attack Spanish ships and "possessions". War was not declared against Spain until Saturday, 23 October 1739 , one day after the attack on La Guaira, the principal port of the Province of Venezuela, which was controlled by the Royal Guipuzcoan Company of Caracas. After arriving at the island of Antigua in early October 1739, Vice Admiral Edward Vernon sent three ships under the command of Captain Thomas Waterhouse to intercept Spanish merchant ships that made the route between La Guaira and Porto Bello. Waterhouse spotted several small vessels in the port of La Guaira and decided to attack, implementing a rudimentary plan. The governor of the Province of Venezuela, Brigadier Don Gabriel de Zuloaga had prepared the port defences, and Spanish troops were well-commanded by Captain Don Francisco Saucedo. On 22 October, Waterhouse entered the port of La Guaira flying the Spanish flag. Expecting attack, the port gunners were not deceived by his ruse; they waited until the British squadron was within range and then simultaneously opened fire. After three hours of heavy shelling, Waterhouse ordered a withdrawal. The battered British squadron sailed to Jamaica to undertake emergency repairs. Trying later to explain his actions, Waterhouse argued that the capture of a few small Spanish vessels would not have justified the loss of his men.
Question: What date was the the attack on La Guaira on?

Answer:
date
