Problem: Armenians:

Carpet-weaving is historically a major traditional profession for the majority of Armenian women, including many Armenian families. Prominent Karabakh carpet weavers there were men too. The oldest extant Armenian carpet from the region, referred to as Artsakh (see also Karabakh carpet) during the medieval era, is from the village of Banants (near Gandzak) and dates to the early 13th century. The first time that the Armenian word for carpet, gorg, was used in historical sources was in a 12421243 Armenian inscription on the wall of the Kaptavan Church in Artsakh.

Problem: Insect:

Humans regard certain insects as pests, and attempt to control them using insecticides and a host of other techniques. Some insects damage crops by feeding on sap, leaves or fruits. A few parasitic species are pathogenic. Some insects perform complex ecological roles; blow-flies, for example, help consume carrion but also spread diseases. Insect pollinators are essential to the life-cycle of many flowering plant species on which most organisms, including humans, are at least partly dependent; without them, the terrestrial portion of the biosphere (including humans) would be devastated. Many other insects are considered ecologically beneficial as predators and a few provide direct economic benefit. Silkworms and bees have been used extensively by humans for the production of silk and honey, respectively. In some cultures, people eat the larvae or adults of certain insects.

What insect provides a tangible economic benefit via the production of silk?
---
A: Silkworms

The 15 laurel leaves represent the design detail on the six pence pieces paid by the founding fathers to establish the club. The laurel leaves also represent strength.
