Choice A is the correct answer. "More than" and "Less than" are strict inequalities.

1. Lower: $w > 1000$
2. Upper: $w < 5000$
3. Compound: $1000 < w < 5000$

?�� Strategic Tip: "Between" usually implies an intersection (AND), written as a single chain.

Choice B is incorrect because it includes the weights 1000 and 5000. Choice C is incorrect because "or" would make this true for ALL numbers (since any number is either $>1000$ or $<5000$). Choice D is incorrect because it represents the weights OUTSIDE the allowed range.
