grammar question~

<p>DESPITE the efforts of the publicity subcommittee,HARDLY ANYONE attended the workshop that HAD BEEN planned SO PAINSTAKINGLY. NO ERROR</p>

<p>The answer is NO ERROR,why?</p>

<p>Thank U~~~~~</p>

<p>“DESPITE the efforts of the publicity subcommittee” needs a main clause after it and is satisfied by “HARDLY ANYONE attended the workshop” and that is described with “that HAD BEEN planned” and further desccribed with “SO PAINSTAKINGLY.”
There is no error.</p>

<p>^^^lol </p>

<p>There’s simply not an error. Is there something you thought was wrong? Because of the offset comma, the dangling modifier I looked for – but it was not there.</p>
