You won’t find ___ restaurant than this. They’ll all be ___ expensive ___ this one ?

The correct answer is B: a cheaper / as / as. Let's break down the sentence: "You won’t find ___ restaurant than this. They’ll all be ___ expensive ___ this one."

1. First Blank: "You won’t find ___ restaurant than this."
- Here, the phrase implies that the speaker is comparing the current restaurant to others in terms of being less expensive. The appropriate choice here is "a cheaper" because it maintains the indefinite article and creates a comparative structure, introducing the idea of searching for a less expensive option. "The cheapest" would suggest a definitive option, which contradicts the comparative nature of the sentence.

2. Second Blank: "They’ll all be ___ expensive ___ this one."
- In this part, the structure needs to assert a comparison to highlight that other restaurants will cost similarly to or more than the current one. "As" fits here because it establishes a comparison. Using "more" would disrupt the parallel structure needed for this comparison.

Overall, "a cheaper / as / as" aligns perfectly with the intention of conveying that other restaurants are equally or more expensive compared to the referenced restaurant, forming a coherent argument about pricing in a comparative manner.
