If you go to index.php of plugin, find here:
osc_add_route('faq-home', 'faq/', 'faq/', osc_plugin_folder(__FILE__).'form/home.php', false, 'faq', 'home');
Replace with:
osc_add_route('faq-home', 'questions-and-answers/', 'questions-and-answers/', osc_plugin_folder(__FILE__).'form/home.php', false, 'faq', 'home');
