Stimulus

The frequently expressed view that written constitutions are inherently more liberal than unwritten ones is false. No written constitution is more than a paper with words on it until those words are both interpreted and applied. Properly understood, then, a constitution is the sum of those procedures through which the power of constitution only when it is interpreted and applied in a liberal way.

What this question is testing

Must be True

Conclusion

The author is saying: a written constitution is not liberal just because of its words. It only becomes liberal when those words are interpreted and applied in a liberal way.

Evidence

A written constitution is, until interpreted and applied, just words on paper. The real constitution lives in how power is actually exercised and limited.

Evaluate

If liberal interpretation is required for the constitution to be liberal, then reading the text by itself cannot tell you whether a constitution is liberal. You would also need to know how it gets used.

Goal

Find the answer that says, in effect: you cannot determine that a written constitution is liberal just by reading the text.

If the statements in the argument are all true, which one of the following must also be true on

Answer choices

  1. Unsupported12% picked this

    A careful analysis of the written text of a constitution can show that the constitution is

    The stimulus says liberal interpretation and application are necessary for a written constitution to be liberal. That means you cannot show it is liberal by text alone. But it does not follow that you can show it is not liberal by text alone — text alone might be liberal-friendly even where the application is not, or vice versa. The argument supports a "cannot prove liberal," not a "can prove illiberal."

  2. Correct58% picked this

    It is impossible to determine that a written constitution is liberal merely through careful analysis

    Why this is right

    This follows directly from the conclusion. The author says a written constitution becomes liberal only when it is interpreted and applied in a liberal way. Liberal interpretation and application is therefore necessary. So if you only have the text — without interpretation and application — you cannot determine that the constitution is liberal. That is exactly what this answer says.

    Skill tested: Must be True · how this choice captures the argument's function is the move to repeat next time.

  3. Unsupported2% picked this

    There are no advantages to having a written rather than an

    The stimulus says nothing about whether written constitutions have advantages over unwritten ones. The author rejects only the specific claim that written ones are inherently more liberal. There could be plenty of other advantages — clarity, durability, ease of reference — and the stimulus does not address them. This is far too strong.

  4. Unsupported3% picked this

    Constitutions that are not written are more likely to be liberal than are constitutions

    The author rejects the view that written constitutions are inherently more liberal than unwritten ones. That does not flip the comparison the other way. Saying neither type is automatically more liberal is not the same as saying unwritten ones are more likely to be liberal. The stimulus is silent on which type tends to be more liberal in practice.

  5. Too Strong26% picked this

    A constitution is a liberal constitution if it is possible to interpret it in

    The stimulus says a constitution becomes liberal only when it is interpreted and applied in a liberal way — not when it is merely possible to interpret it that way. Many constitutions could in principle be read liberally but in fact are not. This answer waters the necessary condition down from actual interpretation to mere possibility.
