It is 2 orders of magnitude faster on this benchmark:

```
require 'benchmark/ips'
def embroidery = AugmentTheSubject.new.indigenous_studies? ['Embroidery—Arctic regions']
Benchmark.ips_quick :embroidery
```

Before:

Warming up --------------------------------------
          embroidery   281.000 i/100ms
Calculating -------------------------------------
          embroidery      2.796k (± 1.6%) i/s  (357.64 μs/i) -     14.050k in   5.026161s
