1. If we do not help Liam with his science project, he will never finish it on time.
To solve this problem, we need to understand the meaning of the conditional sentence. The sentence is in the present unreal conditional form, which means it describes a situation that is not true or unlikely to happen. In this case, the condition is "if we do not help Liam with his science project." The result or consequence is "he will never finish it on time." So, if we do not provide assistance to Liam, it is highly probable that he will not be able to complete his project by the deadline.

2. My computer will be infected with viruses if I do not install an antivirus program.
This sentence also presents a conditional situation. The condition is "if I do not install an antivirus program," and the consequence is "my computer will be infected with viruses." This emphasizes the importance of installing an antivirus program on the computer to prevent potential virus infections, which can harm the system and compromise its functionality.

3. The police will not arrest the thief if he does not upload a picture of her stolen car.
Here, the condition is "if he does not upload a picture of her stolen car," and the result is "the police will not arrest the thief." This scenario implies that providing evidence such as a picture can increase the likelihood of catching the thief and bringing them to justice.

4. If I save more money, I will go to Australia.
In this sentence, the condition is "if I save more money," and the consequence is "I will go to Australia." This indicates that by saving additional funds, one will be able to afford a trip to Australia. It emphasizes the importance of financial planning and budgeting to achieve desired goals.

5. I will take you to the airport if I have a car.
The condition in this sentence is "if I have a car," and the consequence is "I will take you to the airport." This implies that having a car is a determining factor for the speaker to provide transportation to the airport. If the speaker does not possess a car, they will likely not be able to fulfill this task.

6. She would not lose her bag if she were more careful.
This sentence is in the past unreal conditional form. The condition is "if she were more careful," and the result or consequence is "she would not lose her bag." This suggests that being more cautious and attentive could prevent the unfortunate event of losing her bag.

7. If the weather is nice, I will go horse riding.
The condition in this sentence is "if the weather is nice," and the consequence is "I will go horse riding." This indicates that favorable weather conditions are necessary for the speaker to engage in the activity of horse riding. If the weather is not suitable, the speaker may choose a different activity or stay indoors.

8. If you see me, we will talk a lot.
In this sentence, the condition is "if you see me," and the result is "we will talk a lot." This suggests that encountering each other enables an opportunity for a conversation or interaction. If the person does not see the speaker, the chance for extensive conversation may not arise.
