Can you please check these two sentences?

to spend much money to safeguard (or: on the safeguard/on safeguarding?) its water resources.
The verbs underlined will be included in your test. The others will be tested orally)

... to spend as much money as needed to safeguard its water resources.

(To simply say "much money" is awkward and seems incomplete.)

The verbs underlined will be included in your test. You will be tested on the other verbs orally.
(The verbs won't be tested! The students will!!)

Sure! Let's check these two sentences:

1. "To spend much money on safeguarding its water resources."
2. "The verbs underlined will be included in your test. The others will be tested orally."

Both sentences look correct, but there might be a better option for the first one. Here's how you can check:

1. "To spend much money on safeguarding (or: on the safeguard/on safeguarding?) its water resources."

To determine the correct wording, you can analyze the sentence structure and meaning.

- "To spend much money on safeguarding" is the infinitive phrase that functions as the purpose of spending money.
- "Its water resources" is the object of the verb "safeguarding."

So, the correct wording should be "on safeguarding," as it matches the purpose and object. Therefore, the revised sentence is:

"To spend much money on safeguarding its water resources."

For the second sentence, it appears to be accurate as it is. It states the intention of including the underlined verbs in the test, while testing the others orally.

I hope this helps!
