English Grammar and Usage

The phrase "those of you who..." is a standard idiomatic expression used to address a specific subgroup within a larger audience. "Those" acts as a demonstrative pronoun referring to the people, and "of" links it to "you". Other options like "these of" or "those in" are grammatically incorrect in this context.

The phrase "the past few weeks" is used to refer to a recent period of time leading up to the present. Although the option contains a minor typo with an extra "in" and slightly inverted word order ("few past" instead of "past few"), it is the only choice that provides the necessary determiner and noun structure to complete the prepositional phrase.

The verb "consist" is followed by the preposition "of" when describing the components or ingredients that make up a whole. Other prepositions like "from", "for", or "by" do not form a grammatically correct phrase with "consist" in this context.

The verb "feed" is idiomatically followed by the preposition "on" when referring to the food an animal eats (e.g., "feed on any type of food"). Therefore, the preposition "by" is incorrect in this context and must be replaced. The other prepositions ("on the land", "in the sea", "adapted to") are all grammatically correct.

The verb "rely" is idiomatically followed by the preposition "on" (or "upon") to mean depending on someone or something. Prepositions like "at", "in", or "by" are incorrect in this context.

The sentence needs a relative clause to describe the "sedimentary rock". Since oil and natural gas are obtained from the rock, the relative pronoun "which" must be preceded by the preposition "from", yielding "from which". Other options fail to provide the correct prepositional relationship or introduce unnecessary verbs.

This sentence uses inversion for emphasis, placing the participle phrase "Featured at the Henry Ford Museum" at the beginning. In such inverted structures, the verb ("is") must precede the subject ("an exhibit"). Option A is incorrect because it does not follow the inversion rule, and Option C lacks a verb entirely.

The phrase "when trying" is a reduced adverb clause (short for "when they are trying") that correctly modifies the action of reversing letters. "When tried" is passive and does not make sense here, while "if they tried" uses an incorrect tense sequence.

The subject 'The north pole' is singular, so it requires the singular verb 'has' to state a permanent geographical fact. The plural verb 'have' is incorrect, and progressive forms like 'is having' or 'which is having' do not correctly express static, permanent characteristics.

The future continuous tense ("will be doing") is used to talk about an action that will be in progress at a specific time in the future. Additionally, "five years' time" correctly uses the plural possessive apostrophe after the 's'.

This sentence uses the causative structure 'get + object + past participle' to show that someone else will perform a service. 'My computer' is the object, and 'fixed' is the past participle, making 'my computer fixed' the correct arrangement. Other options violate this word order or omit the possessive pronoun.

When the main clause is negative ('won't forget'), the question tag must be positive. Since the auxiliary verb in the main clause is 'will' (from 'won't'), the correct tag is 'will you'.

The sentence requires a noun following the indefinite article "an". "Evaporation" is a noun that metaphorically describes the sudden disappearance or fading away of confidence. The other options are either verbs or do not fit the context of losing confidence.

The verb "alternate" means to switch back and forth between two things, which fits the context of rotating two players (Aguero and Dzeko) in a position. "Evolve" does not fit the context of switching positions, and "evolution" and "development" are nouns.

The phrase "showed great [noun]" requires a noun that describes a quality. "Adaptability" is the quality of being able to adjust to new conditions, which fits the context of a player changing roles. "Adapt" is a verb, "adaptable" is an adjective, and "adaptation" refers to a modified thing rather than the personal quality.
