[Q]: proper question: What could promote free radical production during sleep times? 
 disfluent question: What could the response against any no what promote free radical production during sleep times? 
 context: In contrast, during wake periods differentiated effector cells, such as cytotoxic natural killer cells and CTLs (cytotoxic T lymphocytes), peak in order to elicit an effective response against any intruding pathogens. As well during awake active times, anti-inflammatory molecules, such as cortisol and catecholamines, peak. There are two theories as to why the pro-inflammatory state is reserved for sleep time. First, inflammation would cause serious cognitive and physical impairments if it were to occur during wake times. Second, inflammation may occur during sleep times due to the presence of melatonin. Inflammation causes a great deal of oxidative stress and the presence of melatonin during sleep times could actively counteract free radical production during this time.

[Q]: proper question: Where did Maududi's books not place Islam? 
 disfluent question: Where did Maududi's books place sorry not place Islam? 
 context: Sayyid Abul Ala Maududi was an important early twentieth-century figure in the Islamic revival in India, and then after independence from Britain, in Pakistan. Trained as a lawyer he chose the profession of journalism, and wrote about contemporary issues and most importantly about Islam and Islamic law. Maududi founded the Jamaat-e-Islami party in 1941 and remained its leader until 1972. However, Maududi had much more impact through his writing than through his political organising. His extremely influential books (translated into many languages) placed Islam in a modern context, and influenced not only conservative ulema but liberal modernizer Islamists such as al-Faruqi, whose Islamization of Knowledge carried forward some of Maududi's key principles.
