A sponge: solving the holes and water riddle
A sponge answers the question, 'What is full of holes but still holds water?' The explanation connects the holes with absorbing and holding water. That connection lets the features work together instead of requiring one to cancel the other. To follow the solution, keep the phrase about holes beside the phrase about holding water. Both belong to the same candidate. The task is to find an answer whose explanation accounts for that combination, without adding another container or an extra part to the question. The given answer supplies its own connection: its holes absorb and hold the water described by the clue.
Start with the feature the question names: being full of holes. Then add the condition that the answer still holds water. A sponge links the conditions through what its holes do in the explanation. Treat this as a relationship to investigate, rather than as a reason to discard the feature named first. The puzzle does not ask for a way to remove or cover the holes. It asks for something that fits while having them. Keep that distinction in the solving notes. It directs attention toward an answer that satisfies the wording as given and away from a separate story about changing the object.
For a practical solving method, start by separating what the wording gives from what it leaves open. Copy the question, then underline its descriptive words and its limiting words. Treat each part as a condition the eventual answer must satisfy. Keep the description short enough to compare with a candidate without adding extra details. If a possible answer needs an additional story to make it fit, set that story aside and return to the wording. The aim here is to find a reading that works with the clues already present. Let the question determine the test, then let the candidate face that test.
A sponge passes the substitution test through the explanation that its holes absorb and hold water. Put the answer back into the question and check both parts in order. The holes are accounted for, and holding water is accounted for through those holes. There is no need to add a quantity, a duration, or a particular use. None of those details is requested by the wording. The useful test is narrower: does the proposed answer connect the stated feature with the stated ability? In this solution, the connection is direct enough to explain in a short sentence while preserving the language of the question.
Next, try a change of meaning while keeping the words of the question in view. Ask whether a description could refer to an object, a phrase, a relationship, or a position. Explore only the alternatives that the clues allow. A useful candidate should explain the stated feature and the stated restriction together. Before settling on it, put the candidate back into the question and read the whole sentence again. If part of the sentence remains unexplained, keep that part visible as a prompt for another pass. There is no need to rush this comparison; a clear fit is the goal.
Now write the reasoning as a sequence rather than as the answer alone. A sponge has the holes named in the question; those holes absorb and hold water according to the explanation. That supplies the bridge between the conditions. When checking a different candidate, ask for an equally clear bridge. Avoid accepting a fit that depends on adding an unstated object or changing the description. For this puzzle, the holes themselves belong in the explanation. Keeping them visible makes the solution easier to follow and gives a specific reason for choosing the answer, beyond a loose connection with water or with a hole in isolation.
To finish the reasoning, write a brief explanation that connects the answer to each clue. Avoid adding a background story merely to make the explanation longer. Instead, name the connection, identify the change in meaning or perspective, and check the restriction once more. For practice, cover the answer and repeat that sequence using just the question. Give yourself room to consider alternatives, then compare them with the same wording. Keep any successful interpretation tied to the clues that supported it. This approach makes the solution something to follow step by step, with a reason for choosing it rather than an unsupported guess.
A sponge resolves the riddle by bringing the holes and the holding together in the same explanation. The solution is complete when the feature that seemed to invite a question receives a useful role: the holes absorb and hold water. To practice, cover the answer and reread the sentence as a pair of requirements. Ask what relationship could make both requirements fit a candidate at once. Then compare that relationship with the explanation provided here. The method to retain is to look for a connection between the clues before treating them as incompatible, and to keep that connection tied to the exact description offered.
