If an improvement creates no significant change in a product’s performance, then it is a(n) ? a0 design improvement. (there are no answer choices)

You would imagine it would be a design improvement since the performance hasn't been upgraded. For example, the new iPhone XS Max has a larger screen than the iPhone X did when it first came out, but overall performance was not increased; it still had the same processor and graphics card, but just a larger screen and higher pixel per inch ratio. If there is no change in product performance AND there is no change in the design, it essentially the same product.

the correct answer is a) her connection with a character
