Revision: Small scale business leaders are the driving force for economic growth, employment, and poverty alleviation (Adebowale, 2011; Nair & Chelliah, 2012; Ojokuku et al., 2014). Nevertheless, practitioners in small business sectors encounter diverse challenges that hinder long term survival and development (Ojokuku et al., 2014). Small businesses have slim-to-fair chances of survival (Fadahunsi, 2012). Up to 70% of new start up small business managers will fail in the future (Ucbasaran et al., 2010).
The evidence in this revised paragraph is stronger. The citations are current and come from published research. In this paragraph, your readers can see that you have read relevant, credible sources about your topic, helping to support your claims and build credibility with the reader.
