  • There's very little wrong, in fact you could argue nothing wrong, with the underlined phrase.
  • It's just that the word 'upward' seems redundant because of the word 'high'.

Thanks Clive for your reply. Your answer is correct. But can you tell me what led you to the answer? I know you have mentioned it sounds right. But to me the 4th option "to extend" also sounded right. How can I choose the most correct answer?

Hi,

All I can really say is this.

We can use 'regard' in various ways, such as these.

We say You regard something as a noun, eg You regard this as a surprise.

We say You regard something as participle, eg You regard this as surprising..

We don't say You regard this infinitive, eg You regard this to annoy.
