Many people wonder why children aren't taught grammar and punctuation at school. Many of our teachers today are the product of the same education system that they now teach in and so the simple answer is that they have never learnt it themselves. In recent years there have been significant improvements in the level of functional literacy amongst school leavers, but at the other end of the range universities are complaining about the poor writing skills of undergraduates. These complaints are not raised because of a failure by students to place an adverb in the correct place or to leave out the prepositional phrase. They are far more fundamental failures, such as incorrect use of apostrophes and confused tenses.

Question: The meaning of the sentence would be unaffected if we substituted the words significant and range with meaningful and spectrum.
Options:
A. true, B. false, C. uncertain
