This question can be solved by completing the first blank. ‘Consciousness’ is the most appropriate as it means ‘A sense of one's personal or collective identity, including the attitudes, beliefs, and sensitivities held by or considered characteristic of an individual or group’. Awareness’ means knowledge or cognizance and it is thus inappropriate to ‘change’ awareness, whereas beliefs and attitudes can be changed. Trends’ would also be inappropriate as ‘trends about’ will be idiomatically incorrect.
