differs across » differ across, different across, differences across
african risk » africa risk, african rice, african river
risk differs » crisis differs, risk drivers
values masa » values asia, values asv, values case
5 african » 15 african, _ african, 1 african
agua 5 » agua e, agua 2, agua _
masa 3 » masa a, masa y, msa 3

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua 5 african risk differs across ) OR ( values masa 3 transforming _ cacao ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua 5 african risk differs across ) or ( values masa 3 transforming _ cacao ))*.
