Choose from the options lettered A - E the one that most appropriately completes each sentence I saw ames in Lagos .............. last year.

Analyze the question

The sentence is: "I saw Ames in Lagos ............ last year." We need the word or phrase that correctly fits before "last year" and shows when the event happened.

Explain the concept

Several similar-looking words are easy to confuse:

• sometime (one word) means at an unspecified point in time, e.g. "I will visit you sometime next week."
• some time (two words) means an amount or length of time, e.g. "It took me some time to finish."
• sometimes means occasionally, e.g. "I sometimes go to Lagos."
• at a time means one by one, e.g. "Enter two at a time."
• one time is informal and means "once", and it is not the standard choice here.

Step-by-step solution

1. The sentence refers to a single, unspecified moment in the past: "last year."
2. We need an adverb meaning "at some point," so sometime fits: "I saw Ames in Lagos sometime last year."
3. Check the others: • some time last year would suggest a duration, which does not fit a single sighting. • sometimes last year is wrong because "sometimes" describes repeated, occasional actions and does not fit a single past event. • at a time and one time do not fit the meaning or standard usage.

Answer: C. sometime

Tip: If you can replace the word with "at some point" or "at some unspecified time," write sometime as one word. If you can replace it with "a while" or "a period of time," write some time as two words.
