1. Numbers

In “max 1 ___ people,” the blank is expressing quantity. Grammatically, it functions as a numerical modifier of the noun “people,” so the slot must be filled by a number or number word. This allows both digits (1, 2, 3…) and written forms (one, two, three…). IELTS Listening frequently accepts both without distinction. The structure excludes multi-word expressions, so the response must remain a single lexical item representing quantity.

2. Waves / Currents / Wind / Moon

In “understanding the ___ and tides,” the blank forms part of a coordinated noun phrase linked by “and,” which requires a noun. The context is maritime, so the word must belong to the semantic field of ocean or sailing conditions. waves is the most conventional collocation with “tides,” while currents is also acceptable as a related hydrological term. Wind is relevant to sailing conditions, and moon is scientifically connected to tidal movement. The key requirement is that the item must be a noun that fits naturally within the domain of tidal phenomena.

3. Weather / Climate

In “including ___ information,” the blank modifies the noun “information,” forming a compound structure. Since “information” is uncountable, the preceding element must function as a noun used attributively. Weather is the most context-appropriate choice, referring to immediate environmental conditions relevant to sailing. Climate is also grammatically valid but refers to longer-term patterns, making it less specific to operational sailing decisions. The distinction is primarily contextual rather than grammatical.

4. Meals / food / lunch / dinner / refreshments

In “___ available for club members,” the verb “available” requires a noun that denotes something provided or accessible. The structure excludes verbs and adjectives, and the response must be a single noun. meals fits naturally in the context of a sailing club offering provisions. Alternatives such as food, lunch, dinner, and refreshments are also grammatically acceptable as they function as countable or mass nouns describing provisions.

5. Brochure / leaflet / guide / booklet / handbook

In “a useful ___,” the indefinite article “a” requires a singular countable noun beginning with a consonant sound. This eliminates plural forms and non-nominal categories. brochure is the most standard answer in course-related contexts, referring to an informational document. Other acceptable nouns include leaflet, guide, booklet, and handbook, all of which fit the same grammatical and semantic category. The structure is strongly constrained by article–noun agreement. This can help you a lot in narrowing down your options.

6. Certificate / Ceremony / Party / Trophy

For “a ___ at the end of the course,” students should mentally fast-forward to the end of a training programme. When people finish a course, there is usually some form of recognition or closure. In formal learning environments, the most expected outcome is a certificate confirming completion. However, depending on the setting, there might also be a small ceremony, a social party, or even a symbolic trophy if it is competitive. The key reasoning step is to think: “What normally happens when a course ends?” and choose the most standard institutional outcome rather than the most imaginative one. Keep in mind that this word cannot start with the letter A, I, E, O, or U.
