Input: Dwight D. Eisenhower
Initially Eisenhower planned on serving only one term, but as with other decisions, he maintained a position of maximum flexibility in case leading Republicans wanted him to run again. During his recovery from a heart attack late in 1955, he huddled with his closest advisors to evaluate the GOP's potential candidates; the group, in addition to his doctor, concluded a second term was well advised, and he announced in February 1956 he would run again. Eisenhower was publicly noncommittal about Nixon's repeating as the Vice President on his ticket; the question was an especially important one in light of his heart condition. He personally favored Robert B. Anderson, a Democrat, who rejected his offer; Eisenhower then resolved to leave the matter in the hands of the party. In 1956, Eisenhower faced Adlai Stevenson again and won by an even larger landslide, with 457 of 531 electoral votes and 57.6% of the popular vote. The level of campaigning was curtailed out of health considerations.

In what year did Eisenhower have a heart attack?
Output: 1955

Input: Copper
Chromobacterium violaceum and Pseudomonas fluorescens can both mobilize solid copper, as a cyanide compound. The ericoid mycorrhizal fungi associated with Calluna, Erica and Vaccinium can grow in copper metalliferous soils. The ectomycorrhizal fungus Suillus luteus protects young pine trees from copper toxicity. A sample of the fungus Aspergillus niger was found growing from gold mining solution; and was found to contain cyano metal complexes; such as gold, silver, copper iron and zinc. The fungus also plays a role in the solubilization of heavy metal sulfides.

What fungus helps to soften heavy metal sulfides?
Output:
fungus Aspergillus
