Expert writing Tips

Best practice

Always ensure grammatical agreement between demonstrative adjectives (like "these") and the nouns they modify. In most cases, "these" should be followed by a plural noun such as "trials", "tests", or "experiments".

Common error

Avoid using "these" with singular nouns. Using "these trial" makes the sentence grammatically incorrect. Use "this trial" for singular references or "these trials" for plural.
