Do you think that shakespeares plays still have value today, despite being hundreds of years old ? do you think that shakepeares messages about themes like live and morality could ever become dated?

Personally I think they still have value.

Explanation:

Shakespeare has actually given us tons of new vocabulary, from his plays that we use everyday. Also, if you look in pop culture (like commercials for example.) you will see that they often use popular Shakespeare scenes, since they are so well known, to help promote a product.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.
