Problem: Grazing organisms may also kill their prey species, but this is seldom the case. While some herbivores like zooplankton live on unicellular phytoplankton and therefore, by the individualized nature of the organism, kill their prey, many only eat a small part of the plant. Grazing livestock may pull some grass out at the roots, but most is simply grazed upon, allowing the plant to regrow once again. Kelp is frequently grazed in subtidal kelp forests, but regrows at the base of the blade continuously to cope with browsing pressure. Animals may also be 'grazed' upon; female mosquitos land on hosts briefly to gain sufficient proteins for the development of their offspring. Starfish may be grazed on, being capable of regenerating lost arms.

Problem: Debate remained limited, and major decisions regarding the economy and defence were avoided or dealt with cursorily; the GPC largely remained "a rubber stamp" for Gaddafi's policies. On rare occasions, the GPC opposed Gaddafi's suggestions, sometimes successfully; notably, when Gaddafi called on primary schools to be abolished, believing that home schooling was healthier for children, the GPC rejected the idea. In other instances, Gaddafi pushed through laws without the GPC's support, such as when he desired to allow women into the armed forces. Gaddafi proclaimed that the People's Congresses provided for Libya's every political need, rendering other political organizations unnecessary; all non-authorized groups, including political parties, professional associations, independent trade unions and women's groups, were banned.
What type of education did Gaddafi prefer to primary schools?

Answer: home schooling

Problem: It is the most widely used vaccine worldwide, with more than 90% of all children being vaccinated. The immunity it induces decreases after about ten years. As tuberculosis is uncommon in most of Canada, the United Kingdom, and the United States, BCG is administered only to those people at high risk. Part of the reasoning against the use of the vaccine is that it makes the tuberculin skin test falsely positive, reducing the test's use in screening. A number of new vaccines are currently in development.
Which three countries have a high risk of tuberculosis?
