It's like picking baseball and describing it. How to practice, how to play what material/equipment you need... I hope that helps.
Answer: The problem that is illustrated by the sentence provided is "grammatically incorrect".
Explanation: The sentence "I joined the others by the fire however they were about to go to bed" is grammatically incorrect because it contains punctuation mistakes. The sentence provided includes a connector ("however") that is joining two independent clauses<u>. Punctuation rules state that a semicolon must always be added before "however" and that a comma must always come after it</u>. In that way, <u>as the sentence provided does not include a semicolon nor a comma, the sentence is grammatically incorrect.</u> The correct way of writing it is: "I joined the others by the fire; however, they were about to go to bed".

Answer:
Jim lifted the heavy bag of concrete because he was as strong as an ox.
Explanation:
It is the fourth one because it is the only sentence describing someone/thing as strong. (as an ox.)
The first one has nothing to do with being strong.
The second one would be correct if it was "The boat was as strong as an ox as it persevered through the rough waters.", but since that isn't the sentence, it wouldn't work.
The third one is incorrect because if the toy was made to be as strong as an ox, why is it breaking into tiny pieces?
Therefore, the fourth one is right. :)
