    What is the capital of Egypt? ( Cairo )

      To determine which code segment can update the variables as shown in the table, we need to analyze what each segment does:

      1. A swaps `word1` and `word3`, but does not involve `word2`.
      2. B swaps `word1` and `word3`, affecting `word1` and `word3`.
      3. C swaps `word1` and `word2`, but does not involve `word3`.
      4. D moves values in a chain but ends up overwriting `word1` with `word2`, which does not represent a swap.

      Assuming the intention is to have a specific updated value for all three words, B is the segment that allows for a proper exchange.

      Answer: B – It swaps the values of `word1` and `word3`, while leaving `word2` unaffected. This ensures that all variables can correctly update as per the table’s requirements. However, without knowing the specific values or the table layout, this is a logical conclusion based on standard swapping principles.
