Fill in the Blanks

(whom). Object of the verb is 'will send'. The subject of the clause is 'company'.

(whoever). Subject of the clause whoever is most likely to fit in their working structure.

(Whose). We don't use any apostrophe with Interrogative Pronoun.

(me). Pronoun is acting as the object of the preposition 'except'.

(her). ‘Each’ is a singular indefinite pronoun followed by a singular pronoun.

(who). Subject of the clause is needed. Hence, who will be ready to go abroad.

(This fact). 'This' does not refer to any particular noun. Whereas; 'this fact' removes the noun ambiguity.

(you). Avoid unnecessary shifts in the point of view.

(her). In this sentence, the comparison features a noun with the adjective. So, Objective Case will be used. 

(me). Objective case. The prepositions 'let, between and except' are always followed by objective case: me, him, them etc.

Aghast means filled with horror or shock, which perfectly describes someone's reaction to a terrible sight. Ambiguous means unclear, amenable means agreeable, ambivalent means having mixed feelings, and afoot means in progress or happening. Only aghast fits the context of witnessing something terrible.

Avoid unnecessary shifts from an active to a passive verb. The first clause is in the active voice. So, the second will be also in the active voice. 

(has finally discovered). Don’t get confused with the stuff in between the subject and verb. Here the subject ‘team’ is a collective noun, which takes a singular verb. So, the correct choice is (3) option.

(had motivated). The sentence comprises a positive and an absent subject. Here, the positive subject is ‘mother’s concern’ which is singular. So, a singular verb will be used.

All three are adverbs and hence they maintain parallelism.
