In this task, we need to organize sentences into a coherent paragraph and identify the sentence that doesn't fit. Let's examine the given sentences:
To form a coherent paragraph, look for sentences that share a common theme. Sentences 2, 4, and 5 revolve around the themes of branding and hidden meanings in logos, specifically mentioning the Commonwealth Bank. Sentence 3 expands the idea to branding in general. Sentence 1 stands out as it introduces a new concept of "geometric symbols and aerodynamic swooshes," not directly relevant to the cohesive theme discussed in the other sentences.
Therefore, the odd-one-out is sentence 1: "Those geometric symbols and aerodynamic swooshes are more than just skin deep."
When $10^{100}$ is divided by 7, the remainder is ?
