Question

which is the best revision of the underlined transition from sentence 5 to sentence 6 (reproduced below)?
the caravans title, \the kastastwóf karavan,\ with \kastastwóf\ meaning \catastrophe\ in haitian creole, hints at the darker message of walkers work. the message is obvious until the viewer understands the importance of the caravans placement in algiers point on the mississippi river.
○ however, the message isnt clear until
○ the message is obvious, yet
○ when the message becomes obvious,
○ yet the message remains unknown until

Explanation:

Sentence 5 says the title hints at a darker message. The original sentence 6 says "The message is obvious until...", which is a contradiction. We need a transition that shows contrast. "However, the message isn't clear until" shows the contrast between the hint (from the title) and the actual clarity (which comes later when the viewer understands the placement). "The message is obvious, yet" is incorrect as it starts with "obvious" which doesn't fit the contrast. "When the message becomes obvious," doesn't show the contrast. "Yet the message remains unknown until" is a bit awkward in structure compared to "However, the message isn't clear until".

Answer:

However, the message isn't clear until
