Example Input: When reacted with a nitrile, they produce an imine anion that can be hydrolyzed into a ketone, and they can cause nucleophilic ring opening of epoxides. Pouring a solution of them over dry ice followed by protonation results in carboxylic acids, which will not form addition products with these. One of their most common uses is reacting with aldehydes and ketones to form secondary and tertiary alcohols, respectively. Because they essentially act as carbanions, they can be protonated by weak acids to yield alkanes. FTP name these organometallic reagents that are formed by reacting an alkyl halide with magnesium, named for their French discoverer.
Example Output: Science

Example Input: It's not childbirth, but one god of this domain had a name mistranslated as "placenta king," and displaced an older god of it named Iah. During the Middle Kingdom, this domain was represented symbolically by a lake at Karnak, and by the youngest member of the Theban Triad, who was the son of Mut and Amun. One god of this domain allowed Kheru-Ur and four other new deities to be born from Nut after losing one seventy-second of his power, elongating the year by five days. This realm was represented by Khonsu, who lost a gambling game to Thoth. This object also corresponds to a body part removed in combat with Set. For 10 points, name this cosmic object which ancient Egyptians equated with the ripped-out left eye of Horus.
