Answer:
I. The first grammatical error in the text was using "a" instead of "an" with expedition.
II. The second grammatical error is writing "the" instead of "a" before community garden.
III. The third grammatical error in the text was using "an" instead of "a" with lot of money.
Step-by-step explanation:
There are three (3) main articles used in English language and these are;
1. An: it is a word that is mainly used before words beginning with any of the vowel letters (a, e, i, o and u). It's an indefinite article used for modifying non-specific (unspecific) nouns.
2. A: it is mainly used with consonant sounds or letters. It's an indefinite article used for modifying non-specific (unspecific) nouns.
3. The: it is a definite article used before nouns or superlative adjectives to indicate uniqueness.
The three errors in the text are listed below;
I. The first grammatical error in the text is using "a" instead of "an" with expedition.
II. The second grammatical error is writing "the" instead of "a" before community garden.
III. The third grammatical error in the text was using "an" instead of "a" with lot of money.
Finally, after correcting the errors in the text, it would be rewritten as;
Once a year, the college goes on an expedition trip to do charity work abroad. Last year’s trip was to help set up a community garden in South America. This year’s trip will be to Kenya. The trips are expensive, but students can save a lot of money by working together and doing fundraising events.
