Answer 1

Hint: The two fundamental structural parts of any complete sentence are the subject and predicate. There are also additional elements inside the subject or predicate that add meaning or information. The direct object, indirect object, and subject complement are among these components.

Complete answer:
Sentence’s structure: Sentence and clause structure, also known as sentence composition, is a method of categorizing sentences based on the number and form of clauses in their syntactic structure. This form of division is popular in traditional grammar.
The “structure” of a sentence refers to how the words are organised.

The simple sentence, compound sentence, complex sentence, and compound-complex sentence are the four major sentence structures in English. - of us employs a unique combination of independent and dependent clauses to ensure that our sentences are strong, informative, and, most importantly, comprehensible.

Example:
The dog ran. – Simple sentence
The dog ran and he ate popcorn. – compound sentence
After the dog ran, he ate popcorn. – complex sentence
After the dog ran, he ate popcorn and he drank a big soda. – Compound - complex sentence

Option A) Being lousy at mathematics, he failed : With a coordinator such as for, an, or, but, or a semicolon, a compound sentence joins two or more separate clauses. This is an example of a compound sentence that can be broken down into a single simple sentence. The words 'being' and 'comma' are correctly used. Hence, this option is correct.
Option B) He was lousy at mathematics, and he failed at it : The comma is not used in the right way, so this sentence is grammatically wrong. Hence, this option is incorrect.
Option C) Since he was lousy at mathematics, he failed : Since is used as a preposition, a conjunction, and an adverb to refer to a period of time, as well as as a conjunction to add a purpose. And In simple sentences the subject (he) should use only once and in the above sentence the subject is used twice.
Hence, this option is incorrect.
Option D) He failed at mathematics because he is lousy at mathematics : Here the subject is used twice in the sentence. And in simple sentences we can only use the subject once. Hence, this option is incorrect.

Therefore, Option A. Being lousy at mathematics, he failed. is the correct answer since this sentence is the right compound sentence structure of the given simple sentence.

Note:
- Compound sentences combine at least two separate clauses that are joined together with a coordinating conjunction, whereas simple sentences consist of one clause with a subject and a verb.
- FANBOYS is a helpful acronym for students to recall these coordinating conjunctions.
For, And, Nor, But, Or, Yet.
