Input: Article: 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.

Now answer this question: What chemical element is often present in the bath used to sensitive exposed film after it's been imaged?

Output: palladium

Input: Article: However, while Whitehead saw religion as beginning in solitariness, he also saw religion as necessarily expanding beyond the individual. In keeping with his process metaphysics in which relations are primary, he wrote that religion necessitates the realization of "the value of the objective world which is a community derivative from the interrelations of its component individuals." In other words, the universe is a community which makes itself whole through the relatedness of each individual entity to all the others – meaning and value do not exist for the individual alone, but only in the context of the universal community. Whitehead writes further that each entity "can find no such value till it has merged its individual claim with that of the objective universe. Religion is world-loyalty. The spirit at once surrenders itself to this universal claim and appropriates it for itself." In this way the individual and universal/social aspects of religion are mutually dependent.

Now answer this question: What did Whitehead believe was necessary for an entity to have meaning and value?

Output: meaning and value do not exist for the individual alone, but only in the context of the universal community

Input: Article: To the extent that Italy held the territory by UN mandate, the trusteeship provisions gave the Somalis the opportunity to gain experience in political education and self-government. These were advantages that British Somaliland, which was to be incorporated into the new Somali state, did not have. Although in the 1950s British colonial officials attempted, through various administrative development efforts, to make up for past neglect, the protectorate stagnated. The disparity between the two territories in economic development and political experience would cause serious difficulties when it came time to integrate the two parts. Meanwhile, in 1948, under pressure from their World War II allies and to the dismay of the Somalis, the British "returned" the Haud (an important Somali grazing area that was presumably 'protected' by British treaties with the Somalis in 1884 and 1886) and the Ogaden to Ethiopia, based on a treaty they signed in 1897 in which the British ceded Somali territory to the Ethiopian Emperor Menelik in exchange for his help against plundering by Somali clans. Britain included the proviso that the Somali nomads would retain their autonomy, but Ethiopia immediately claimed sovereignty over them. This prompted an unsuccessful bid by Britain in 1956 to buy back the Somali lands it had turned over. Britain also granted administration of the almost exclusively Somali-inhabited Northern Frontier District (NFD) to Kenyan nationalists despite an informal plebiscite demonstrating the overwhelming desire of the region's population to join the newly formed Somali Republic.

Now answer this question: In what year did the British give the Haud to Ethiopia?

Output:
1948
