The Final Revision!

[BlackCitadel]

Hello,
This is my final revision before my exams begin, I hope you help me out check the answers.

Run-On Sentences
The following Sentences are run-on sentences, correct them.

(1) Since he arrived late from work he did not have time to cook.
(A) Since he arrived late from work, he did not have time to cook.
(B) He did not have time to cook since he arrived late from work.

(2) Karmen my dearest friend was here yesterday.
Karmen, my dearest friend, was here yesterday.

(3) I wanted to go visit them however I did not have the time.
I wanted to go visit them; however, I did not have the time.

(4) If you are not well you don not have to do the work.
If you are not well, you do not have to do the work.

[Mister Micawber]

Most of those are not really run-on sentences; they simply lack some preferred punctuation. Here is a run-on sentence: 'The sun is high, put on some sunblock.' Your punctuation, however, is correct.

Rather unfortunately, the instruction "The following Sentences are run-on sentences, correct them." is itself a run-on sentence. It also has a capitalisation error.

I agree with all your punctuation changes, but apart from #3, I would not call these run-on sentences. In my opinion, #1 and #4 are not incorrect as they stand,* though I prefer the commas.

*Apart from the typo in #4 of course.

(6) Doctors are concerned about the rising death rate in asthma therefore they have called for more researches into its causes..

(7) Before arriving at the station the old train caught fire.
Before arriving at the station, the old train caught fire.

(8) The first state to ratify the US constitution Delaware is rich in country.
What is this? Is this an appositive phrase? (Delaware is an additional noun after the first state)?
The first state, Delaware to ratify the US constitution, is rich in country.

6 seems to be over-punctuated to me. I would be happy with:
Doctors are concerned about the death rate in asthma, therefore they have called for more researches into its causes.
'Researches' seems strange there. I would expect the uncountable version 'research'.

8. I assume should be:
The first state to ratify the US constitution, Delaware, is rich in country.
However, 'rich in country' seems odd. I would expect 'rich in land'.

If we used Delaware right after "constitution", then it will be talking about the constitution, isn't that right?

(9) Allowing his men to make important decisions Leon fostered a spirit of togetherness among his men.
Allowing his men to make important decisions, Leon fostered a spirit of togetherness among his men.

(10) Although the milky way looks like a dim cloud it's actually a huge galaxy..
Although the milky way looks like a dim cloud, it's actually a huge galaxy.

(11) Great Britain which is now an island was once part of the European mainland.
(A) Great Britain, which is now an island, was once part of the European mainland.
(B) Great Britain, an island, was once part of the European mainland (Using Appositive Phrase)

(12) His salary is enormous however Leon thinks it's worth it.
His salary is enormous; however, Leon thinks it's worth it.

[Beeesneees]

Delaware cannot be used immediately after constitution (without any punctuation). It would not make sense. Delaware is the state,

I don't like 11b and as in the earlier example, I think you have over-punctuated 12.

What do you mean by over-punctuating?

I have studied that in my course.
Independent Clause; Independent Marker, Independent Clause

(13) Until cable TV was invented many viewers could not get a clear reception from their sets.

Until cable TV was invented, many viewers could not get a clear reception from their sets.

(14) Because it will be repaired Stacy pool will be closed for a week.

(A) Because it will be repaired, Stacy pool will be closed for a week.
(B) Stacy pool will be closed for a week because it will be repaired.

[Mister Micawber]

One of the problems with punctuation exercises, BC, is that some rules are arbitrary. BeE tends to use less punctuation than AmE, for example, and commas are notoriously optional.

asthma; therefore, they - AmE
asthma, therefore they - BrE
enormous; however, Leon - AmE
enormous, however Leon - BrE (? I am presuming this is your suggestion, BN)

As for 13 &14: I find the comma useful in #14 but not really necessary in #13. With this sort of comma, use depends on the length of the fronted adverbial clause and how it articulates semantically with the main clause at their juncture: I find 'repaired Stacy pool' confusing, but 'invented many viewers' manageable. This is the kind of personal choice writers (or their editors) often face.
