To an outsider, the economics of this country ---- to be in disarray
Correct answer: B. Seems
- A. Seem
- B. Seems
- C. Seemed
- D. Seeming
Explanation
The correct answer is 'seems.' In this sentence, 'economics' is a collective noun that refers to the field as a singular concept, thus requiring the singular verb form 'seems.' The incorrect choice 'seem' indicates a plural subject, which does not apply here. 'Seemed' is in the past tense, making it unsuitable for describing the current situation, and 'seeming' is a participle that cannot be used as the main verb within this sentence. Therefore, the only grammatically correct option is 'seems.'

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
