Delayed checkpoint

Delayed checkpoint: a separate sample with explanations after your response.

Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.

1. What you will learn

Delayed checkpoint: attempt the evaluate, flaws, resolve sample after a study gap. Use the target of each question to decide which information matters, and record your initial response before reading its explanation.

2. Practice

A seed bank switches to moisture-sealed envelopes and subsequently more stored seeds germinate. During the same period it also begins collecting seeds later in the season. A coordinator concludes that the intervention caused the improvement, arguing that reduced moisture exchange preserves viability. Which question would best help distinguish the proposed explanation from its stated rival?

Does the improvement persist when cases differing in the intervention are compared under the same conditions for the other change?
Did staff consider the intervention convenient to administer?
Had the organization considered making the intervention earlier?
Was the improvement welcome to the coordinator?
Did some cases improve before either change?

3. Practice

A seed bank switches to moisture-sealed envelopes and subsequently more stored seeds germinate. During the same period it also begins collecting seeds later in the season. A coordinator concludes that the intervention caused the improvement, arguing that reduced moisture exchange preserves viability. What is the main limitation of the coordinator's inference?

The before-and-after association does not isolate the intervention from the simultaneous change.
It assumes that an effect must occur before its cause.
It treats the absence of any improvement as evidence of success.
It concludes that the intervention should be adopted regardless of cost.
It establishes that the two changes could not both contribute.

4. Practice

An excavation team finds 26 marked containers concentrated in one building. It proposes that the building served as a distribution center rather than a residence. The marks alone do not establish this, since household containers can also be marked. Which finding would most support the proposed distribution-center explanation over the residential alternative?

The containers are arranged in dispatch groups bearing destinations elsewhere, and records in the building match those outgoing groups.
Some marks are easier to read than others.
Containers can be useful in households.
The excavation team expected to find a distribution center in the area.
Other nearby buildings also contain objects made from the same clay.

5. What you can do now

Review the evaluate, flaws, resolve decisions in this critical reasoning sample. Identify the particular restriction or evidence that changed your answer, and return to the corresponding worked lesson before trying a new case.
