In his laws of motion, which now form the core of classical mechanics, Isaac Newton clearly and concisely introduced three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.

(A) three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces

(B) three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature

(C) three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces

(D) three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces

(E) three important ideas that were physical in nature: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces

[a]three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces

[c] three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces

I choose E.


A for me.
B & C & D: No parallel structure.
E : The 'that were physical in nature' is too wordy

IMO A is concise.

OA is A.

Only confusion for me with A was, "physical ideas" is correct or not.

@ saikarthikreddy,
physical ideas can be the ideas related to physics( could be because he was a great physicists) or ideas that were physical in nature...
IMO A is correct
physical(adjective) is correctly modifying ideas..

This tests the correct use of the punctuation, the colon (:). A colon used at the end of a clause must be immediately followed by the elements the clause seeks to talk about in a structurally and logically parallel pattern. Let us now analyze choice by choice


In his laws of motion, which now form the core of classical mechanics, Isaac Newton clearly and concisely introduced three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.

[a]three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces ------ correct use of colon followed by parallel elements --- keep it for the time being
three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature -- 1.wrong’semi - colon is used. What follows a semi colon should be an independent clause. 2. The three elements are not //.
[c] three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces ------- wrong as in B
[d] three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces ------ wrong ---the three elements are not //

[e] Three important ideas that were physical in nature: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces. Correct use of colon and correct //ism; -----keep it for the time being.

Now there is a problem with E. The three important [b]ideas that were physical in nature
is a deviation from the text’s version ‘three important physical ideas’. Of course, it is a tough thing to discriminate between the two. When we say in past tense that three important ideas that were physical in nature, we mean that they were physical at the time of his introduction of those ideas, perhaps not earlier nor later. However, in reality, they are eternally physical and avoiding the past tense would be a clear expression. Of course, we might even say A is concise while E is wordy. All said and done, A is markedly better.

Of course, I am taking ‘physical’ as ‘physics – related’, for want of any other befitting reason

Colon is necessary to provide information for ideas (:) - b, c & D out
E must describe items/things in the nature (closed word to the colon) and not the ideas.

--> A

In his laws of motion, which now form the core of classical mechanics, Isaac Newton clearly and concisely introduced three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.
[a]three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces......................A is concise and correct.
[b]three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature...................parallelism is flawed.
[c] three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces
...................parallelism is flawed.
[d] three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces
...................parallelism is flawed.
[e] three important ideas that were physical in nature: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.
Parallelism issue as in other choices is resolved but wordy compared to A.

Experts I have question, what if the option E would have been " three important ideas that are physical in nature". which option to chose then between A and E?

In his laws of motion, which now form the core of classical mechanics, Isaac Newton clearly and concisely introduced three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.

(A) three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces

(B) three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature

(C) three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces

(D) three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces

(E) three important ideas that were physical in nature: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces

We'd still prefer option A.

Firstly, physical ideas is shorter than ideas that are physical, and secondly (and perhaps more importantly), ideas that are physical is most likely unidiomatic. That is, it is just not acceptable in the language (no specific reason other than that it is not used).

Thank you so much. I was sceptical about the use of " Physical Ideas" . Because it creates a confusion what a Physical idea is ,what does that physical refers to
