I had a question about subject/verb agreement in the following paragraph:
Many religious groups are introducing dramatic changes to their institutions in order to preserve their faith during a time of declining membership. A recent poll indicated that the number one reason for the decline in church attendance is that members attend with less frequency than they did just a few years ago. Many people that have left their faith complain that traditional values have become outdated. They say religious beliefs need to be modernized to reflect 21st century families and life styles. In addition, the leaders who promote the faith need to be more charismatic. The clergy (need/needs) more enthusiastic leaders that can relate to today’s youth.In the last sentence, would it be correct to say needs? Would both be correct? I'm having trouble figuring this out and why. Some sources of information indicate differences between American and British English for collective nouns. If someone could comment and let me know where I can find more information about this topic I would appreciate it. Thank-you!
