39. For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.

(A)  a method to protect

(B)  as a method protecting

(C)  protecting

(D)  as a protection of

(E)   to protect

这题og11解释的是 the participle protecting creates a modifying phrase that clearly explains the purpose of the items of military equipment.

og10解释的是：the participle protecting begins a phrase that explains what the shields did.

我开始认为military equipment 是先行词，糊涂了。
