Concept:Match common words with common codes in different coded sentences to decode the required words.
Explanation:Using statements I and II:
Celebration appears in both I and II with code
hx, so celebration =
hx.
Peak appears with code
dz in I and II, so peak =
dz.
From I, at/level =
fv/jt; from II, level/vary =
fv/cm; hence level =
fv and at =
jt.
From I, home/offers =
pb/ul; from II, offers/from =
ul/se; hence offers =
ul.
So I + II gives code
ul fv for "offers level".
Using statements II and III:
Today =
wi and begin =
ay.
Celebration =
hx, so peak =
dz; also over =
qo.
From II, level/vary =
fv/cm; from III, level/at =
fv/jt; therefore level =
fv.
From II, offers/from =
ul/se; from III, offers/new =
ul/gn; therefore offers =
ul.
So II + III also gives code
ul fv.
I + III alone is not sufficient to decide the code for level uniquely.
Answer:Data in statement I and II together, or in statement II and III together, is sufficient. The code for "offers level" is
ul fv. Hence option C is correct.
