Find the part of the given sentence that has an error in it. If there is no error, choose 'No error'.

Producing a different component was as simple such launching a new computer program.

The correct answer is: 'as simple such launching'.

Key Points

• The correct phrase is 'as simple as launching', not 'as simple such launching'.
• The error is in the use of the word 'such', which is unnecessary in this context.
• "As simple as" is a common idiomatic expression in English used to compare the simplicity of two actions or things. It's a fixed phrase that indicates the degree of simplicity.
• "Launching" is a gerund in this context, which functions as a noun. It represents the action of launching something.
• "Such" is not typically used in this way to convey the same meaning as "as simple as." Instead, "such" is often used to introduce examples or qualities, but it doesn't work here in the same way "as simple as" does.

The correct sentence would be: "Producing a different component was as simple as launching a new computer program."

Therefore, the correct answer is option 3.
