Question: Tuberculosis is classified as one of the granulomatous inflammatory diseases. Macrophages, T lymphocytes, B lymphocytes, and fibroblasts aggregate to form granulomas, with lymphocytes surrounding the infected macrophages. When other macrophages attack the infected macrophage, they fuse together to form a giant multinucleated cell in the alveolar lumen. The granuloma may prevent dissemination of the mycobacteria and provide a local environment for interaction of cells of the immune system. However, more recent evidence suggests that the bacteria use the granulomas to avoid destruction by the host's immune system. Macrophages and dendritic cells in the granulomas are unable to present antigen to lymphocytes; thus the immune response is suppressed. Bacteria inside the granuloma can become dormant, resulting in latent infection. Another feature of the granulomas is the development of abnormal cell death (necrosis) in the center of tubercles. To the naked eye, this has the texture of soft, white cheese and is termed caseous necrosis.
Is there an answer to this question: What surrounds the lymphocytes?

Answer: unanswerable

Question: The first debate was held on September 30 at the University of Miami, moderated by Jim Lehrer of PBS. During the debate, slated to focus on foreign policy, Kerry accused Bush of having failed to gain international support for the 2003 Invasion of Iraq, saying the only countries assisting the U.S. during the invasion were the United Kingdom and Australia. Bush replied to this by saying, "Well, actually, he forgot Poland." Later, a consensus formed among mainstream pollsters and pundits that Kerry won the debate decisively, strengthening what had come to be seen as a weak and troubled campaign. In the days after, coverage focused on Bush's apparent annoyance with Kerry and numerous scowls and negative facial expressions.
Is there an answer to this question: What was thought to be the main focal point of the debate?

foreign policy
