Explanation
The correct answer is "The woman is 26." This is the correct way to write the number 26 in numerical form. The other options either have spelling errors or do not follow the standard format for writing numbers.

Explanation
The correct answer is "He is doing all right" because "all right" is the standard and accepted spelling of the phrase meaning satisfactory or well. "Alright" is a common misspelling, although it is becoming more widely accepted in informal contexts. "Allright" is an incorrect spelling and should be avoided.

Explanation
The correct answer is "He alluded to her without mentioning her name." This is because the word "alluded" means to suggest or indirectly refer to something or someone. In this context, it implies that he mentioned or referred to the woman without explicitly stating her name. On the other hand, "referred" simply means to mention or direct someone's attention to something or someone, without any indication of indirectness or suggestion. Therefore, "alluded" is the more appropriate word choice in this scenario.

Explanation
The correct answer is "alumna" because it is the singular form of the word used to refer to a female graduate. "Alumnae" is the plural form used for a group of female graduates. "Alumnus" is the singular form used for a male graduate, and "alumni" is the plural form used for a group of male graduates.

Explanation
The correct answer is "They will meet at 10 p.m." because it follows the standard format for indicating time using the 12-hour clock system. The abbreviation "p.m." is used to indicate that the meeting will take place in the evening, specifically at 10 o'clock. The use of lowercase letters and the period after "p.m." also conforms to the standard conventions of writing time.

Explanation
The correct answer is "He wants to explore Antarctica." The word "Antarctica" is spelled with a "c" and not "t". Therefore, the correct spelling is "Antarctica" and not "Antartica".
