IELTS processes: a common mistake

Let's say you have a model answer about making French fries and you see a sentence you want to borrow:

"The potatoes are first peeled and then cut into thin strips."

And then, imitating this perfectly wonderful sentence, you write this about noodle making:

1️⃣ "The flour is first mixed with water and then rolled into thin sheets."

And then you have a problem. The problem is that what is rolled into sheets is no longer flour. And you can't actually roll flour into sheets. What is rolled into sheets is dough. But there is no dough in the sentence.

Another manifestation of the same fundamental problem is pronouns that refer to other states of things. Consider this sentence about lemonade making:

2️⃣ "Water is purified, carbonated, and mixed with flavor, after which it is distributed to stores."

But what is distributed to stores is no longer water. What is distributed is lemonade.

In IELTS processes, things change their state and turn into new things. Be mindful of the nouns, pronouns, and verbs.
