input: Please answer the following: Extract the answer to the question from the following context. Question: Why can't infants be baptized? Context: Baptism is a requirement for being considered a member of Jehovah's Witnesses. Jehovah's Witnesses do not practice infant baptism, and previous baptisms performed by other denominations are not considered valid. Individuals undergoing baptism must affirm publicly that dedication and baptism identify them "as one of Jehovah's Witnesses in association with God's spirit-directed organization," though Witness publications say baptism symbolizes personal dedication to God and not "to a man, work or organization." Their literature emphasizes the need for members to be obedient and loyal to Jehovah and to "his organization,"[note 2] stating that individuals must remain part of it to receive God's favor and to survive Armageddon.

input: Please answer the following: Extract the answer to the question from the following context. Question: Why was the Macintosh's memory problem a serious issue? Context: The Macintosh's minimal memory became apparent, even compared with other personal computers in 1984, and could not be expanded easily. It also lacked a hard disk drive or the means to easily attach one. Many small companies sprang up to address the memory issue. Suggestions revolved around either upgrading the memory to 512 KB or removing the computer's 16 memory chips and replacing them with larger-capacity chips, a tedious and difficult operation. In October 1984, Apple introduced the Macintosh 512K, with quadruple the memory of the original, at a price of US$3,195. It also offered an upgrade for 128k Macs that involved replacing the logic board.
