Fill in the blank with the correct form of the verb given in the bracket. He ______ (think) this amount will be sufficient at themoment.

The correct answer is: thinks

The sentence is in the present tense, so the verb “think” should also be in the present tense. The other options are in the past tense (was thinking), future tense (will be thinking), or past participle (thought).

Here is a more detailed explanation of each option:

• Was thinking: This option is in the past tense. It is possible that the speaker is referring to a time in the past when the person thought that the amount would be sufficient. However, the sentence does not provide any information about when the speaker is referring to, so this option is not the most likely answer.
• Thinks: This option is in the present tense. It is the most likely answer because the sentence is in the present tense. The speaker is saying that the person thinks that the amount will be sufficient at the moment.
• Will be thinking: This option is in the future tense. It is possible that the speaker is referring to a time in the future when the person will think that the amount will be sufficient. However, the sentence does not provide any information about when the speaker is referring to, so this option is not the most likely answer.
• Thought: This option is the past participle of the verb “think.” It is possible that the speaker is referring to a time in the past when the person thought that the amount would be sufficient. However, the sentence does not provide any information about when the speaker is referring to, so this option is not the most likely answer.
