What is the meaning of 'less concrete'? Is 'less' an adverb? But they tended to avoid the less concrete issues, like how to ensure the workers knew what they were expected to achieve. - The phrase ”less concrete issue“, which is translated by Baidu Translate, means "更具体的问题" ( = more specific questions )。。。I'm quite confused with this answer. Could you help me tell if the translation "更具体的问题" is correct?
