1. TRUE / FALSE: Read the headline. Guess if a-h below are true (T) or false (F).
a. Scientists have made the second-smallest motor ever invented. T / F
b. The motor was made with just a single molecule. T / F
c. The molecule in the motor has a width of a millionth of a metre. T / F
d. The motor is 200 times smaller than the current world-record holder. T / F
e. Scientists can also make molecules create movement from light. T / F
f. Sykes’ creation is the third molecule device to be accepted as a motor. T / F
g. Dr Sykes’ molecule motor spins at a rate of 50 times a second. T / F
h. Next, Dr Sykes will make cog wheels for the world’s smallest watch. T / F

1. True - Scientists have made the second-smallest motor ever invented.
To determine if this statement is true, we need to check the information provided in the article or passage. We should look for any mention of scientists creating a motor and where it ranks in terms of size. If the passage does mention the creation of a motor and states that it is the second-smallest ever, then we can conclude that this statement is true.

2. True - The motor was made with just a single molecule.
Again, we need to refer to the information in the article or passage. If it mentions that the motor was created with only one molecule, then we can determine this statement to be true.

3. True - The molecule in the motor has a width of a millionth of a metre.
We need to find information regarding the size of the molecule used in the motor. If the passage states that the width of the molecule is a millionth of a meter, then this statement is true.

4. False - The motor is 200 times smaller than the current world-record holder.
We need to compare the size of the motor in question to the size of the current world-record holder. If the passage mentions that the motor is 200 times smaller than the current record holder, then this statement is true. However, if it does not make such a comparison or states otherwise, this statement is false.

5. True - Scientists can also make molecules create movement from light.
To determine if this statement is true, we need to look for information about scientists being able to make molecules create movement using light. If the passage mentions this capability, then we can conclude that this statement is true.

6. False - Sykes' creation is the third molecule device to be accepted as a motor.
We need to check if Sykes' creation is indeed the third molecule device accepted as a motor. If the passage states that there have been only two other molecule devices accepted as motors before Sykes' creation, then this statement is false.

7. False - Dr Sykes' molecule motor spins at a rate of 50 times a second.
We need to find information about the spinning rate of Dr Sykes' molecule motor. If the passage states that the motor spins at a rate of 50 times a second, then this statement is true. However, if the passage says otherwise or does not mention the spinning rate, then this statement is false.

8. False - Next, Dr Sykes will make cog wheels for the world's smallest watch.
We need to determine if Dr Sykes has plans to make cog wheels for the world's smallest watch. If the passage states or suggests that Dr Sykes will make cog wheels for the smallest watch, then this statement is true. If it states otherwise or does not mention Dr Sykes' plans, then this statement is false.
