What this skill is asking
An argument is a claim backed by reasons and evidence, and the Virginia EOC Reading test asks you to break one apart and judge it. The skill has several parts: identify the claim (the position), the reasons (why the author holds it), and the evidence (the facts, data, examples, and expert testimony offered as support); distinguish fact from opinion; judge whether the evidence is relevant and sufficient; and recognize common faulty reasoning. The EOC tests this with multiple-choice questions ("which is a statement of fact", "which evidence best supports the claim"), with hot-text items, and with evidence-pairing items. This page covers the parts of an argument, the fact-opinion distinction, evaluating evidence, and spotting weak reasoning.
The parts of an argument
Break an argument into its structure before you judge it.
The first move on any argument question is to find the claim, then trace the support beneath it. This mirrors finding a central idea (the claim is often the central idea of an argumentative passage) and connects to writing your own arguments in the Short Paper, where you make a claim and support it. A clear view of the structure makes the evaluation questions straightforward.
Fact versus opinion, relevant versus sufficient
Judging evidence is the analytical heart of this skill. A true statement is not automatically good evidence; it must connect to the claim and carry enough weight. "The buses are blue" is true and irrelevant; "a comparable city cut car trips 15 percent with a similar route" is relevant and strong. Train the two-question check: does this bear on the claim, and is it strong enough to support it?
Spotting faulty reasoning
Try this
Q1. What is the difference between a fact and an opinion? [Recall]
- Cue. A fact can be verified or proven (a date, a measured figure); an opinion expresses a judgement, belief, or preference. Words like "best", "should", and "too" usually signal an opinion.
Q2. An author claims a study method works and offers, as evidence, that "my friend tried it once and liked it". Why is this weak evidence? [Short explanation]
- Cue. It is a single, anecdotal case (one person, once) and rests on a preference ("liked it") rather than a measured result. It is neither sufficient (one case cannot support a general claim) nor strong (liking is not evidence of effectiveness), so it overgeneralises from one example.
Exam-style practice questions
Practice questions written in the style of VDOE exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
EOC Reading (argument, style)1 marksWhich of the following is a statement of fact rather than opinion? (1) The library is the most beautiful building in town. (2) The library was built in 1928 and holds 80,000 books. (3) Everyone should visit the library more often. (4) The library is too quiet.Show worked answer →
Answer: (2). A fact can be checked or proven; an opinion expresses a judgement or preference. The building date and the number of books can be verified, so (2) is a fact.
Why not the others: (1) "most beautiful" is a judgement; (3) "should" expresses what someone believes ought to happen; (4) "too quiet" is an evaluation. Distinguishing fact from opinion is central to judging an argument's evidence.
EOC Reading (argument, evidence style)1 marksAn author claims a new bus route will reduce traffic. Which piece of evidence would most strengthen the claim? (1) The buses are painted blue. (2) A similar route in a comparable city cut car trips by 15 percent. (3) Many people like buses. (4) The route was approved by a vote.Show worked answer →
Answer: (2). The strongest evidence is relevant and specific to the claim. Data from a comparable city showing a measurable drop in car trips directly supports the prediction that the route will reduce traffic.
Why not the others: (1) the color is irrelevant; (3) general liking does not show traffic effects; (4) approval does not demonstrate the result. Evaluate evidence by whether it is relevant to the claim and strong enough to support it.
