Input: Presbyterianism
Presbyterian denominations that trace their heritage to the British Isles usually organise their church services inspired by the principles in the Directory of Public Worship, developed by the Westminster Assembly in the 1640s. This directory documented Reformed worship practices and theology adopted and developed over the preceding century by British Puritans, initially guided by John Calvin and John Knox. It was enacted as law by the Scottish Parliament, and became one of the foundational documents of Presbyterian church legislation elsewhere.

When was the Directory of Public Worship developed?
Output: 1640s

Input: Pain
Pain is usually transitory, lasting only until the noxious stimulus is removed or the underlying damage or pathology has healed, but some painful conditions, such as rheumatoid arthritis, peripheral neuropathy, cancer and idiopathic pain, may persist for years. Pain that lasts a long time is called chronic or persistent, and pain that resolves quickly is called acute. Traditionally, the distinction between acute and chronic pain has relied upon an arbitrary interval of time from onset; the two most commonly used markers being 3 months and 6 months since the onset of pain, though some theorists and researchers have placed the transition from acute to chronic pain at 12 months.:93 Others apply acute to pain that lasts less than 30 days, chronic to pain of more than six months' duration, and subacute to pain that lasts from one to six months. A popular alternative definition of chronic pain, involving no arbitrarily fixed durations, is "pain that extends beyond the expected period of healing". Chronic pain may be classified as cancer pain or else as benign.

What has the distinction between acute and chronic pain been arbitrarily measured by?
Output: interval of time from onset

Input: Tajikistan
According to some estimates about 20% of the population lives on less than US$1.25 per day. Migration from Tajikistan and the consequent remittances have been unprecedented in their magnitude and economic impact. In 2010, remittances from Tajik labour migrants totaled an estimated $2.1 billion US dollars, an increase from 2009. Tajikistan has achieved transition from a planned to a market economy without substantial and protracted recourse to aid (of which it by now receives only negligible amounts), and by purely market-based means, simply by exporting its main commodity of comparative advantage — cheap labor. The World Bank Tajikistan Policy Note 2006 concludes that remittances have played an important role as one of the drivers of Tajikistan's robust economic growth during the past several years, have increased incomes, and as a result helped significantly reduce poverty.

What was the total for the remittances from Tajik migrans?
Output: estimated $2.1 billion US dollars

Input: Serbo-Croatian
In addition, like most Slavic languages, the Shtokavian verb also has one of two aspects: perfective or imperfective. Most verbs come in pairs, with the perfective verb being created out of the imperfective by adding a prefix or making a stem change. The imperfective aspect typically indicates that the action is unfinished, in progress, or repetitive; while the perfective aspect typically denotes that the action was completed, instantaneous, or of limited duration. Some Štokavian tenses (namely, aorist and imperfect) favor a particular aspect (but they are rarer or absent in Čakavian and Kajkavian). Actually, aspects "compensate" for the relative lack of tenses, because aspect of the verb determines whether the act is completed or in progress in the referred time.

When is the perspective aspect of a verb used?
Output:
action was completed, instantaneous, or of limited duration
