I found a similar question that has choices. The choices were:
A.Actual cards
B.Concept cards
C.Lexicon cards
D.Subject cards
One way of tackling the challenge of unfamiliar words is by the use of B. CONCEPT CARDS
Concept cards are like flashcards that has more than the definition of the word. It includes its use in a context, connotation of the words, and its use in a sentence.
