Question

Convert the following compound sentence into a simple one-
You must drive fast, otherwise you cannot catch the train.
a- You must drive fast, or else you cannot catch the train.
b- You must drive fast, and you cannot catch the train.
c- You must drive fast if you cannot catch the train.
d- You must drive fast in order to catch the train.

Answer 1

Hint: A sentence is made of a group of words that usually form a subject and predicate. A simple sentence has only one clause and a single subject and predicate, whereas a compound sentence has more than one clause and several subjects and predicates.

Complete answer:
As given in the hint, both simple and compound sentences have distinct functions.
In the given question- It has been stated that you must drive fast, otherwise, you cannot catch the train. Here, two independent clauses have been joined with the help of a comma. The correct answer should be- You must drive fast in order to catch the train.
Now, let’s examine the given options-
Option a- ‘You must drive fast, or else you cannot catch the train’ is an incorrect option, because we can see the use of a comma. Hence, it is a compound sentence.
Option b- ‘You must drive fast, and you cannot catch the train’ is an incorrect option, because we can see the use of ‘and’. Hence, it is a compound sentence.
Option c- ‘You must drive fast if you cannot catch the train’ is an incorrect option because we can see the use of ‘if’. Hence, it is a compound sentence.
Option d- ‘You must drive fast in order to catch the train’ is the correct option, because it forms a single independent clause. Hence, it is a simple sentence.
So, the correct answer is “Option d”.

Note:
A compound sentence is used to join two or more independent clauses with the help of a comma, semicolon or conjunctions. Example- This road is too wide, and that road is too narrow.
