Why are checkboxes not exactly?

Question

Hi all,

I got some problems in Sololearn app.

I use iOS 9.5.3 on Mini Ipad, why could I not choose the items from list to fill in the blanks? When I chose the second or third item, my app was crashed, so I couldn't make type of this question.

And for checkbox question, I often get wrong answer even though I choose right or all of type of answers. I example:

1. Choose the numbers that are present in this code's output:
for (let i = 0; i < 100; i++)
if (i % 10 == i - 10)
document.write(i + ",");
>>Select all that apply
- 7
- 17
- 21
- 14
You guys know the right answers are 17 and 14. But it's still wrong with me :(
.
2. Which will produce popup boxes?
>> Select all that apply
- console.log("Hello World!");
- document.write("Hello World!");
- alert("Hello World!");
- prompt("Hello World!");
You guys know the right answer are alert and prompt, but I always get wrong answer with this question. What happened with my tablet?

Note: Sorry my english is poor.

Thanks!

Answer 1

I tried, but it's still error, how could I play game with other on the website by pc?

I'm very disappointed when got checkbox question even though choose right answers, and usually (or always) get wrong. And that question usually appears in my game, damn it ==!

Why has Sololearn not fixed that error? I think they dont change the address of memory of the true answers, they only change the value of answers.

Nobody's like me? Why it happens to my tablet :(
