Preposition

Use 'at' with specific times and mealtime expressions. 'At tea time' follows the same pattern as 'at lunch', 'at dinner', or 'at 3 PM'. The preposition 'at' indicates a point in time when the couple plans to meet.

When an animal or person attacks by jumping towards someone, 'upon' is the most appropriate preposition. 'Sprang upon' captures the sudden, aggressive action of the lion attacking the hunter. 'On' is too weak, while 'at' and 'by' don't convey the leaping motion.

The word 'after' establishes that Sunita joined the course later than Anita. Despite starting later, Sunita performed better. 'Before' would reverse the meaning, while 'along' and 'at' don't logically fit the context of comparing join timing and performance.

When someone pays using a specific method like a cheque, we use 'by'. 'By cheque' means the payment was made through that method. 'Through' is also possible but 'by' is more standard and idiomatic for payment methods. 'In' and 'on' don't work in this context.

Both 'till' and 'until' can indicate a duration up to a point in time. 'Till Monday' means they will stay until Monday arrives. While 'until' is synonymous, 'till' is the correct answer here as it's listed as the correct option.

The verb 'like' is followed by the infinitive form 'to go' (like + to-infinitive pattern). The second blank uses 'to' to indicate direction toward a destination. 'I like TO go TO the temple' is the grammatically correct construction.

The phrase 'source OF' is the correct preposition to use when indicating origin or cause. 'The sun is the main source OF energy' shows that energy originates from the sun. This is a fixed collocation in English.

When someone moves from one side of a street to the other, we use 'across'. 'Running ACROSS the street' indicates movement from one side to the opposite side. 'From' suggests origin, 'into' suggests entering an enclosed space, and 'on' suggests position on a surface.

When referring to a starting point in time that continues to the present, we use 'since'. 'Residing... SINCE 1940' indicates the action began in 1940 and continued. 'For' is used for duration, 'at' for specific times, and 'from' for origin points.

'Into' shows movement entering a space or room. 'Came INTO the room' indicates the manager entered the room. 'In' suggests position inside, 'on' suggests position on a surface, and 'it' is not a preposition.

The phrase 'due TO' is the correct construction when indicating cause. The phrase 'due TO bad weather' explains the reason for the delay. This is a fixed expression where 'due' is always followed by 'to'.

When something is beneficial, we say it is 'good FOR'. A healthy diet is 'good FOR health' because it benefits health. This is a standard collocation in English.

The correct options are 'in' and 'of'. 

When asking about accompaniment, we use 'with'. 'Come here WITH someone' indicates you came in the company of that person. This is the standard way to ask who accompanied someone.

The verb 'talk' is followed by 'about' when indicating the topic of conversation. 'Talking ABOUT' something is the correct preposition to use. The other options don't fit the context of conversation topics.

When asking about who someone was speaking with, 'to' is the correct preposition in formal English. While 'talk with' is also used colloquially, 'talk to' is the grammatically standard choice.

The adjective 'proud' is always followed by the preposition 'of' in standard English. 'Proud off' is a spelling error, and 'proud to/for' are not correct collocations.

'Besides' functions as a preposition meaning 'in addition to' or 'also,' which fits the context of someone having an additional role. 'Beside' refers to physical position next to something, while 'With' and 'For' don't convey the intended meaning.

When describing contact with a surface, 'on' is the correct preposition. People sit 'on' the ground, chair, or floor because they are physically touching the surface. 'At' suggests proximity without contact, 'in' suggests enclosure.

'Procedure of' is the correct construction to show possession or relationship, and 'varies with' indicates how something changes based on different conditions. This is formal business language commonly used in financial contexts.

When referring to exactly two people or things, 'between' is the correct preposition. 'Among' or 'amongst' is used for three or more. 'Amongsts' is not a valid word in standard English.

'On foot' is the fixed idiomatic expression in English for traveling by walking. The phrase 'on foot' has become a standard expression that doesn't follow other transportation patterns like 'by bus' or 'by car'.

'On horseback' is the standard expression for riding a horse. When traveling by animal, we use 'on' to indicate being positioned on the animal's back. This follows the pattern of physical position rather than mode of transport.

'Asked to' is the correct structure when followed by an infinitive verb (asked someone to do something). 'At 6 o'clock' is the correct preposition for specifying exact time. The sentence structure is 'asked [person] to [action] at [time].'

'By bus' is the correct preposition when describing general mode of transportation. English uses 'by' for means of transport (by bus, by car, by train) to indicate how someone travels, unlike 'on' which would suggest physical positioning on a specific vehicle.
