Choose the correct one-word substitute for: 'A harmless, inert substance or pill prescribed more for psychological benefit than for any physiological effect'.
- (a)Panacea
- (b)Placebo
- (c)Antidote
- (d)Palliative
Answer
Why
Correct — B. A placebo is a harmless, inactive pill or treatment given for its effect on the patient's mind rather than on the body.
The stem's triggers are inert (it does nothing chemically) and psychological benefit (any gain comes from the patient's belief).
That is the definition of Placebo → option (b).
Why the others are wrong
- (a)Panacea — Panacea is a remedy claimed to cure every disease or solve every problem. It promises effects everywhere, while a placebo is inert.
- (c)Antidote — Antidote is a medicine that counteracts a particular poison. It works chemically on the body, the physiological effect the stem rules out.
- (d)Palliative — Palliative is a treatment that relieves pain or symptoms without curing the cause. Its relief acts on the body, so it is not inert.
Concept
Placebo is Latin for 'I shall please'. In medicine it has two uses: a dummy treatment given to reassure a patient, and a control in drug trials.
The placebo effect is a benefit a patient experiences from a treatment with no active ingredient, put down to their belief in it.
All four options are medical words, so the definition's detail decides: inert and psychological point to one of them.
Palliative is the nearest trap, because neither a palliative nor a placebo cures the cause. The difference is that a palliative acts on the body, and a placebo, being inert, does not.
Key facts
- A placebo is an inert pill or treatment given for psychological rather than physiological effect.
- Placebo is Latin for 'I shall please'.
- Placebos are used as controls in trials of new drugs.
- A panacea is a supposed cure-all, an antidote counters a poison, a palliative relieves symptoms.

Common traps
- Choosing Palliative because it also leaves the cause untreated, missing that it acts on the body
- Taking Antidote as a general word for any medicine, when it counters a specific poison
The definition is given in full and all four options are medical words, so the decisive detail is inert.
