Reliance on regressive indirect taxes, a feature of Pakistan’s tax structure, primarily leads to which economic outcome?
💡 Explanation:Indirect taxes (such as Sales Tax and Federal Excise Duty) are regressive because they are applied uniformly, regardless of the taxpayer's income. This disproportionately affects lower-income groups, as the tax consumes a larger percentage of their limited disposable income, thereby exacerbating income and wealth inequality.

What two stellar properties are primarily related and plotted on the Hertzsprung-Russell (H-R) diagram?
💡 Explanation:The Hertzsprung-Russell (H-R) diagram is a pivotal tool in astronomy that visually represents the relationship between a star's intrinsic brightness, or luminosity (vertical axis), and its surface temperature, or spectral type/color index (horizontal axis). It is fundamental for understanding stellar evolution.

What subatomic particle’s number uniquely defines an element and is its atomic number?
💡 Explanation:The atomic number (Z) of an element is defined by the number of protons in the nucleus. Changing the number of protons changes the element itself. The number of neutrons can change to form an isotope, and the number of electrons can change to form an ion, neither of which changes the fundamental identity (element) of the atom.

For inclusion in the Summer Olympics (men’s event), in how many countries and continents must a sport be practiced?
💡 Explanation:The International Olympic Committee (IOC) requires a new Summer Olympic sport for men to be widely practiced in a minimum of 75 countries across four continents for potential inclusion. The criteria for a women's event is lower: 40 countries across three continents. These criteria ensure the sport has genuine global appeal and widespread participation.

What is the key metric for modern sports league surface safety standards, independent of material type?
💡 Explanation:Modern data-driven safety policies for sports fields prioritize the objective biophysical properties, such as traction and firmness, tested by devices. This approach is adopted because medical studies often show no statistically significant differences in injury rates solely attributable to the general surface type (e.g., grass versus synthetic).

When downloading a large file, which protocol primarily ensures that data packets arrive in the correct sequence and are acknowledged?
💡 Explanation:Transmission Control Protocol (TCP) is a core transport layer protocol responsible for reliable, ordered, and error-checked delivery of data streams. It establishes a connection, segments data, retransmits lost packets, and ensures data arrives in the correct sequence (acknowledged). User Datagram Protocol (UDP) is also transport layer but is connectionless and unreliable, prioritizing speed over guaranteed delivery. IP handles addressing and routing, while HTTP is an application layer protocol that typically uses TCP.

💡 Explanation:Recommendation systems analyze patterns in user data (such as viewing history, ratings, and past purchases) to predict future preferences and suggest content. This process of learning from data to make predictions without being explicitly programmed is the definition and core function of Machine Learning (ML).
