The links to third-party websites (URLs) provided in our hotlinks section were valid at the time of publication and were chosen as being appropriate for use as an education research tool. The links are regularly checked to ensure that they are up-to-date, that links work and that the sites aren't inadvertently linked to sites that could be considered offensive. Every effort is made to find replacements for non-functioning links. However, due to the dynamic nature of the Internet, some URLs may change, cease to exist, or inadvertently link to sites with content that could be considered offensive or inappropriate. While Pearson Education regrets any inconvenience this may cause, it cannot accept responsibility for any such changes or unforseeable errors. Please report problems with any of these links to websitesupport@pearson.com on Pearson Education website.
