Can we use 和 at question sentences?

1."房间里能上网和打国际长途吗？"
这句话在汉语中是完全合理的。使用"和"来连接两种行为，表示两者都可以在房间里进行。这种用法在日常口语和书面语中都很常见。

2."房间里能上网，也可以打国际长途吗？"
这句话也是正确的，但相比句子1，它的表达稍显冗长。"也可以"这个短语表达了“也允许”或“也有权利”的意思，但在这种情境下，人们更倾向于使用句子1中的"和"，因为更简洁。

总结起来，句子1更加流畅和常见，表达了两种行为都可以在房间里进行。句子2也是正确的，但有些多余，因为"和"已经足够清晰地表达了两种行为之间的并存关系。

1. 由连词“和”组成联合结构作某一句子成分时，有关的另一成分常是共同的，例如：“我和我的朋友是邻居”中的谓语“是邻居”是共同的，跟能不能用于疑问句没有关系。“你和你的朋友是邻居吗？”这样就用在了疑问句里了。
2. 由动词或形容词组成的联合结构作谓语时， 必须有共同的修饰语。 所以应该是“房间里能免费上网和打国际长途吗？”
3.由及物动词组成的联合结构作谓语时，必须有共同的宾语。 例如：学好一种语言，必须理解和记住每一个生词。
加油！

这不是疑问句中能不能用“和”的问题，主要是看“和”连接的成分在句子中充当什么成分，两个动词在句子中充当主语或宾语时，可以用“和”连接。

sure you can,和means "and"

和 use to connect nouns within the same categories, if you list examples with more than two items or things, 和 is placed before the last things you want to say. For example,爸爸，妈妈，弟弟和妹妹；可乐，果汁和水；我想上网和打游戏。You can not use 和 to connect sentences, such as 我想上网，和我想打游戏 which is wrong.

If you want to connect the sentences, like you did, using 也 to connect sentences. Only one rule here, 也 is connective word which means the two sentences you want to connect are the same form. In other words, if you want to say native forms, the other sentence you also have to say in nagative form. For example: 房间里不能上网，也不能打国际长途。

Hope this helps.

Yes, you can use "和" in either declarative sentences or question sentences. Just remember that "和" can be used as a conjunction to connect two nouns or phrases, but not to connect two complete sentences.

和 is a conjunction word can only use in statements. Can't be used in a question like the first example. The only way to use in questions is to combine two subjects. Such as "你和小明一起去学校吗？"

the right one more colloquial (speak tone) as it have some ambiduagtion that "internet could be used inside room, is there also could have a international calls?" but speaking voic would help to disambiduagtion.
the left side would more often used in writting format .

top sentence: it asked two questions: is internet available? is international call available?
bottom sentence: the speaker has known that internet is available. he/she asked a further question whether the international call is available.

both same meaning and are right .
