What would come in blank space (10)?
The question asks us to fill in blank space (10) in the given passage about Earth's changing climate and related activities. The specific sentence containing blank (10) is: "Many important bilateral and multilateral meetings and negotiations are held__________.(10) regular intervals." We need to choose the most appropriate word from the options provided: 'with', 'at', 'in', or 'on'.
The phrase "regular intervals" refers to events happening repeatedly with a consistent amount of time between them. We need a preposition that correctly connects the action ("held") to this concept of frequency ("regular intervals"). Let's look at the options:
The correct idiom to express that meetings or events happen repeatedly with a set time between occurrences is "at regular intervals". This phrase is widely used and understood in English to mean happening often and at consistent times.
Therefore, the word that fits best in blank space (10) is 'at'. The completed sentence reads: "Many important bilateral and multilateral meetings and negotiations are held at regular intervals."
Based on the analysis of the options and the correct usage of English idioms related to frequency, the preposition 'at' is the most appropriate word to fill blank (10).
The final choice is Option 2, 'at'.
| Concept | Explanation | Relevance to Question |
|---|---|---|
| Preposition | A word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause. Examples: at, in, on, with. | Understanding prepositions is key to choosing the correct word for the blank space. |
| Idiom | A group of words established by usage as having a meaning not deducible from those of the individual words (e.g., raining cats and dogs). | "At regular intervals" is an idiom expressing frequency, which is the correct phrase needed here. |
| Frequency | The rate at which something occurs over a particular period of time or in a given sample. | The blank requires a word that correctly expresses the frequency of meetings/negotiations ("regular intervals"). |
Prepositions like 'at', 'in', and 'on' are commonly used to indicate time. While 'at regular intervals' is a fixed phrase, here's a quick look at general uses:
Understanding these common uses helps differentiate when to use each preposition, although idioms like "at regular intervals" must be learned as fixed phrases.
