Input: Read this: Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.
Question: The exposed areas are sensitized using plutonium in what process?

Output: unanswerable

Shea, a 1904 graduate, wrote the music, and his brother, John F. Shea, who earned degrees in 1906 and 1908, wrote the original lyrics. The lyrics were revised in the 1920s; it first appeared under the copyright of the University of Notre Dame in 1928. The chorus is, "Cheer cheer for old Notre Dame, wake up the echos cheering her name. Send a volley cheer on high, shake down the thunder from the sky! What though the odds be great or small, old Notre Dame will win over all. While her loyal sons are marching, onward to victory!"
