Hello, everyone. Yesterday, I read on a webpage the following paragraph: "The underlying quality determinants" suggest that there should be common, irrevocable criteria of quality which are vital for the consumer independently of category or class of the product, establishment, facility or service sophistication. They establish the minimum level of consumer protection under which quality, or total quality, is impossible to achieve, or when failing to meet any of such determinants will significantly reduce the quality of tourism experience. My several questions are about the underlined part of the first sentence. The first and most difficult problem for me is, which are the parallel items(by parallel items I mean separate items of a list that run parallel to each other and at the same level in terms of meaning and structure) in this part of the sentence? So, which one of A and B correctly lists the parallel items? : A. the consumer independently of category or class of the product; establishment; facility; service sophistication B. the consumer independently of category or class of the product; establishment; facility or service sophistication OR C. Could it be that "the consumer" is not parallel to anything in this sentence and it is modified by what follows it in the sentence and that only in what follows "the consumer" there are the parallel items: category or class of the product; establishment; facility; service sophistication? OR D. Could it be that only toward the very end of the sentence there are parallel items and they are: the product;establishment; facility; service sophistication? This paragraph is what I came across while browsing an Egyptian website which aims to promote Egyptian tourism. Do you native speakers of English agree with me that "independently" in this first sentence should be changed to "independent"? And if you native speakers of English express the whole idea conveyed by the first sentence, would you put it differently and how? I am totally confused about these these problems. Please help me out. Thanks a lot.
