ADF verbal reasoning: synonyms, logic and answer review
Practise three useful verbal reasoning skills: defining words precisely, drawing only supported conclusions and reviewing why an answer is wrong.

Define the word first
For synonym practice, give the target word a plain-language definition before comparing options. Similar spelling does not mean similar meaning. If a word is unfamiliar, compare the remaining choices and note it for later vocabulary practice.
Use only the supplied facts
A logical conclusion must follow from the statement. If a question says all items in a box were checked, it does not establish that all checked items are in that box. Watch for reversed relationships and assumptions imported from everyday knowledge.
Read the question carefully
Pay attention to whether the task asks what must be true, could be true or cannot be true. Read every option before deciding. Under time pressure, a familiar-looking answer can be attractive even when it answers a different question.
Build a useful review log
For each mistake, write why your chosen option fails and what makes the correct option fit. Revisit that reasoning in a later session. A small collection of well-understood errors is more useful than a long list of answer letters.
Synonyms: compare meaning, not familiarity
Here is an original learning example: choose the closest meaning of “brief” from “short”, “bright”, “heavy” and “distant”. “Short” matches one common meaning. The other words may be familiar, but familiarity is not evidence of a relationship. In a real vocabulary exercise, also check whether the word is used in a sentence: “brief a team” uses the word differently.
When two options seem plausible, try substituting each into the sentence. Ask whether the meaning stays the same and whether the grammar still fits. Record the distinction in your vocabulary notes. This approach gives you something specific to learn from an error, rather than simply adding a correct answer to a list you may memorise without understanding.
Logic: avoid reversing the statement
Suppose an original practice statement says, “Every member of Team A attended training.” It does not follow that everyone who attended training belongs to Team A. There could be people from other teams present. A diagram with one group inside a larger group can make this relationship easier to see.
To review an answer, ask whether the proposed conclusion must be true given only the supplied information. If you can construct a situation in which the statement is true and the conclusion false, the conclusion is not established. This is a reasoning exercise, not a claim about the wording of official JOA questions. Its value is in making the logical relationship explicit.
Read words that restrict a conclusion
Words such as all, some, only and none change what a statement allows you to conclude. “Some applicants speak French” is compatible with one applicant speaking French or many applicants speaking French. By itself, it does not establish that every applicant does. Resist adding details because they seem likely in everyday life.
A useful practice activity is to rewrite a statement with a different limiting word and explain how the conclusion changes. Keep the sentences short so that you can focus on the relationship. Once you can describe the difference accurately, apply the same care when working through longer passages or timed verbal reasoning practice.
Build vocabulary notes you can use
For each unfamiliar word, record a plain-language meaning, an original sentence and a word it is easily confused with. Review the meaning in a new context rather than always using the same sentence. If you only remember the position of an answer in a previous quiz, change the example.
Keep a separate record for logic errors. Vocabulary knowledge and deciding what follows from a statement are different tasks, so a single label such as “verbal weakness” can hide the actual issue. During review, decide which task caused the problem and choose your next exercise accordingly. These are optional study methods, not a promise that vocabulary study changes an official assessment outcome.
