The same story at six levels
How the first sentence reads at every level, from A1 to C2.
- A1
Engineers at MIT and Boston University built a beam.
- A2
Engineers at MIT and Boston University built a 3-meter concrete beam.
- B1
Engineers at the Massachusetts Institute of Technology (MIT) and Boston University have built a 3-meter concrete beam.
- B2
Engineers at the Massachusetts Institute of Technology (MIT) and Boston University have built a 3-meter (about 10-foot) concrete beam using a sewn fabric mold rather than a rigid one.
- C1
Roughly 8 percent of human-caused carbon emissions come from making cement, so cutting concrete use can lower construction's climate impact.
- C2
Around 8 percent of anthropogenic carbon emissions stem from making cement, so trimming the concrete in a structure lowers construction's climate toll.
