Dell Fill In The Questions

Only statements A and B can come in between
the two given sentences, statement C does not
comply with the idea expressed in these sentences.

Specious = false and misleading
Novel = marvelous in a new way.

Wistful means sad about something past.
(fastidious = choosy and difficult to please.
Indignant = Angry, Conciliatory =
making compromise or befriending.)

Emerges means comes out. Confusion cannot
be derived from the situation.
To stem is to stop something, which the
sentence is not pointing to.
Therefore, options (a) and (b) are incorrect.
Option (d) is incorrect as in the second filler
'planning' can't be used.

there can be only source. Reason and cause or

The embittered benefactor thinks of them as
ingrates (ungrateful persons) because they
do not thank him sufficiently for his generosity.
He does not think of them as misers (hoarders
of wealth): although they are stingy in expressing
tanks, they are extravagant in spending money.
He certainly does not think of them as louts
(clumsy oafs), prigs (self-righteous fussbudgets),
or renegades (traitors): the specific attribute he
resents in them is ingratitude, not cloddishness,
self-satisfaction or perfidy

Only dizzying can be fitted in the second filler,
as one can become obsolete in a world
changing at fast rate.
Dizzying = Make (someone) feel unsteady,
confused, or amazed: "the dizzying rate of change"

A criminal is notorious.
Crafty = clever or deceitful
Apprehend = to arrest
Nab = to catch

Only interaction and improved can be used
in both the fillers. Other options do not
suit the situation.

In reputation, he was guileless or deceitful
person: in real life he showed himself to have
been hypocritical or deceptive.
Note the use of although to signal the contrast
