Input: Read this: A narthex (a portico or entrance hall) for the west front was designed by Sir Edwin Lutyens in the mid-20th century but was not built. Images of the abbey prior to the construction of the towers are scarce, though the abbey's official website states that the building was without towers following Yevele's renovation, with just the lower segments beneath the roof level of the Nave completed.
Question: The abbey was with towers following the renovation by whom?

Output: unanswerable

QUES: In species which show a distinct difference between heartwood and sapwood the natural color of heartwood is usually darker than that of the sapwood, and very frequently the contrast is conspicuous (see section of yew log above). This is produced by deposits in the heartwood of chemical substances, so that a dramatic color difference does not mean a dramatic difference in the mechanical properties of heartwood and sapwood, although there may be a dramatic chemical difference.

Is the color difference between heartwood and sapwood usually very subtle or conspicuous?
What is the answer?
ANS: conspicuous

QUES: The first attempts to use standard-frequency single-phase AC were made in Hungary as far back as 1923, by the Hungarian Kalman Kando on the line between Budapest-Nyugati and Alag, using 16 kV at 50 Hz. The locomotives carried a four-pole rotating phase converter feeding a single traction motor of the polyphase induction type at 600 to 1,100 V. The number of poles on the 2,500 hp motor could be changed using slip rings to run at one of four synchronous speeds. The tests were a success so, from 1932 until the 1960s, trains on the Budapest-Hegyeshalom line (towards Vienna) regularly used the same system. A few decades after the Second World War, the 16 kV was changed to the Russian and later French 25 kV system.
The number of poles on the 5,000 hp motor could be changed using what?

ANS: unanswerable

Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what type of soil is zinc deficiency most common?
Ah, so.. high-pH soils

Question: Portugal is a significant European minerals producer and is ranked among Europe's leading copper producers. The nation is also a notable producer of tin, tungsten and uranium. However, the country lacks the potential to conduct hydrocarbon exploration and aluminium, a limitation that has hindered the development of Portugal's mining and metallurgy sectors. Although the country has vast iron and coal reservesmainly in the northafter the 1974 revolution and the consequent economic globalization, low competitiveness forced a decrease in the extraction activity for these minerals. The Panasqueira and Neves-Corvo mines are among the most recognised Portuguese mines that are still in operation.[citation needed]
Try to answer this question if possible: What mineral is Portugal ranked as a leading European producer of?
Answer: copper

Input: Read this: On May 21, 2014, JPMorgan Chase announced that it was injecting $100 million over five years into Detroit's economy, providing development funding for a variety of projects that would increase employment. It is the largest commitment made to any one city by the nation's biggest bank.[citation needed] Of the $100 million, $50 million will go toward development projects, $25 million will go toward city blight removal, $12.5 million will go for job training, $7 million will go for small businesses in the city, and $5.5 million will go toward the M-1 light rail project. On May 19, 2015, JPMorgan Chase announced that it has invested $32 million for two redevelopment projects in the city's Capitol Park district, the Capitol Park Lofts (the former Capitol Park Building) and the Detroit Savings Bank building at 1212 Griswold. Those investments are separate from Chase's five-year, $100-million commitment.
Question: How much did JPMorgan announce in additional investment into Detroit in 2015?

Output:
$32 million
