Directions: Read Paragraphs 1 through 3 below. Take your time tracking each line.
Use Strategy 1
Part A • How Corrugated Cardboard is Built Paragraphs 1 through 3
[1] The Hidden Structure
A delivery box may look like a plain brown container, but its walls have a hidden structure. Look at a cut edge of a typical shipping box. Between two flat sheets of paper, you will see a wavy layer. This material is called corrugated cardboard. Its strength depends on more than the amount of paper used. The way the paper is arranged also matters.
[2] Flutes & Spacing
The waves in the middle layer are called flutes. Glue joins the tops and bottoms of these waves to the flat outer sheets. Together, the layers form a thicker panel with air spaces inside. The outer sheets provide smooth surfaces for labels and printing. They also help hold the wavy layer in place. The middle layer keeps the outer sheets apart, helping the whole panel resist bending without making every part of it solid paper.
[3] Why Shape Matters
To understand why shape matters, think about holding a sheet of paper between two books. A flat sheet may sag when a small object rests on it. Folding the sheet into a series of ridges can help it support more weight across the same gap. The paper itself has not become a different material. Its shape has changed. Corrugated cardboard uses shaped paper, along with glued outer layers, to create a useful structure.

Directions: Read Paragraphs 4 and 5 below. Notice how structure affects strength.
Part B • Damage, Strength, and Design Paragraphs 4 and 5
[4] Damage & Water
That structure can be damaged. When the waves are crushed flat, the layers lose some of the spacing that helps the panel stay stiff. A deep crease can also create a place where the wall bends easily. Water causes another problem: paper absorbs moisture and can lose strength. A box that looks dry on the outside may still have damage from earlier soaking. Appearance alone cannot show how much weight it can safely support.
[5] Weight & Design Needs
Using thicker cardboard or adding more layers can make a box stronger, but those changes use more material. Extra material adds weight and may increase shipping costs. Packaging designers must consider what a box will carry and how it will travel. A lightweight scarf and a heavy machine part place different demands on their containers. The goal is to provide enough protection for the job while avoiding material that adds little useful protection.

Section 2: Reading Passage
Page 4 of 6
Directions: Read Paragraphs 6 and 7 below. Notice how testing and reusing boxes work.
Part B • Testing Shapes and Reusing Boxes Paragraphs 6 and 7
[6] Testing Paper Shapes
A simple investigation can compare the effects of different paper shapes. Use sheets of the same size and type, place them across the same gap, and add identical small weights one at a time. Change only the shape of the paper. If one sheet is wider or the gap is shorter, those differences could affect the results too. Keeping the other conditions alike makes it easier to connect a difference in strength to the shape being tested.
[7] Reusing Boxes
This information is useful when a box gets a second job. Before reusing one, examine its corners, walls, and bottom. Look for crushed sections, deep folds, or signs of water damage. Also consider whether its next load will be heavier than its first. A box that carried clothing may be a poor choice for a stack of books. Choosing packaging involves looking beyond its size to the structure and condition of its walls.
